Before becoming an Adobe Experience Manager (AEM) Sites Developer Expert, it’s crucial to build a strong technical foundation. This part focuses on the essential skills, tools, and concepts that serve as prerequisites before diving into the AEM ecosystem. By investing time into mastering these basics, you can approach AEM’s architecture and development tools with confidence, which sets the stage for becoming an expert developer.
Understanding the Role of an AEM Developer
An AEM Sites Developer is a web development professional skilled in building scalable digital experiences using Adobe Experience Manager. These developers design templates, authoring tools, workflows, and user interfaces to deliver rich web experiences. However, becoming a true expert in this space means going beyond just building pages—it requires deep technical knowledge of AEM’s underlying frameworks, content repository, and tools.
AEM experts also contribute to architectural decisions, enforce coding standards, and often mentor junior developers. The journey to this level begins with proficiency in core web technologies.
Mastery of Java and Object-Oriented Programming
Since AEM is built on Java, a solid grasp of the Java language is essential. Developers should focus on understanding object-oriented programming (OOP) concepts including encapsulation, inheritance, polymorphism, abstraction, and composition.
Java knowledge must extend beyond syntax. You should understand how to design clean, maintainable code using design patterns. Experience with collections, exception handling, input/output operations, generics, annotations, and multi-threading will also be useful. Java classes and interfaces form the building blocks of AEM’s backend logic, especially in custom services and Sling Models.
Understanding the Java Virtual Machine (JVM), garbage collection, memory management, and class loading is also valuable. These concepts help developers optimise application performance and troubleshoot runtime issues.
Frontend Proficiency: HTML, CSS, and JavaScript Basics
Frontend development is a critical part of AEM site creation. Proficiency in HTML and CSS is necessary to structure and style web pages properly. You must be able to create responsive designs using CSS Grid and Flexbox and understand how layout and content elements interact with each other.
In AEM, frontend code is often written using the HTML Template Language (HTL), formerly known as Sightly. While HTL simplifies frontend logic, it is essential to know when and how to integrate with JavaScript and how to keep your frontend code clean and efficient.
Although JavaScript is not a major component in the backend-heavy world of AEM, basic familiarity with the DOM, event handling, and vanilla JavaScript will help when implementing interactive UI components or client-side validation.
Core Web Development Principles and CMS Knowledge
Before diving into AEM development, a foundational understanding of how websites work is key. This includes how HTTP requests and responses function, how client-server interactions are structured, and how assets (CSS, JavaScript, images) are delivered. Understanding RESTful principles will also prove useful when dealing with AEM’s headless capabilities or custom APIs.
AEM is a content management system at its core, so it’s helpful to understand how CMS platforms work. Learn about content hierarchies, permissions, content versioning, and reusable components. These concepts are essential when designing scalable systems within AEM.
Getting Familiar with Sling and JCR
One of the most important backend frameworks in AEM is Sling. Sling is responsible for resolving URLs to content resources stored in the Java Content Repository (JCR) and executing scripts to render responses. In practical terms, Sling allows developers to map incoming URLs to components and templates in the AEM repository.
Learning the basics of Sling includes understanding how:
- Request URLs are mapped to nodes in the content repository
- Sling selects scripts (HTL, JSP, etc.) based on resource types
- Selectors, suffixes, and extensions influence the rendering path
- Sling Models provide a clean way to expose backend logic to HTL
Additionally, AEM uses a hierarchical content store based on the JCR standard. Developers must understand how nodes, properties, and paths work in JCR. Learning how to query content using XPath, SQL2, or QueryBuilder is fundamental when building dynamic pages or data-driven components.
Understanding Maven and Build Automation
AEM projects are typically managed using Apache Maven. Maven is a build automation tool that compiles code, packages AEM content into deployable artifacts, and manages dependencies.
Developers should be able to:
- Understand Maven project structures and modules
- Configure the pom.xml file for dependencies and build plugins
- Use Maven profiles to manage different build environments (e.g., dev, stage, prod)
- Integrate unit testing frameworks into the build process
By automating the build process, Maven ensures that code is consistently compiled and deployed across environments. Familiarity with the AEM Project Archetype is also important, as this tool generates project templates that conform to Adobe’s best practices.
Version Control with Git
Version control is essential in any modern development environment. AEM developers must be proficient in using Git to manage source code and collaborate with team members. Skills should include:
- Branching strategies (feature branches, release branches)
- Merging and resolving conflicts
- Reverting changes and managing history
- Creating meaningful commit messages
- Using .gitignore files effectively
Many AEM teams integrate Git with CI/CD tools to automate testing and deployments. A good grasp of Git workflows ensures seamless collaboration and minimal disruption during releases.
Developing with Security in Mind
Security is a critical aspect of web development, and AEM is no exception. Understanding basic security concepts helps protect both the application and its users. Developers should be familiar with:
- Cross-site scripting (XSS) and how to mitigate it in HTL templates
- Cross-site request forgery (CSRF) protection
- Content Security Policies (CSP)
- Access Control Lists (ACLs) in AEM for role-based access
- Secure session and token management
By adopting secure coding practices from the beginning, you build applications that are resilient to attacks and easier to audit later.
Setting Up a Local AEM Environment
Practical experience is vital for learning. Adobe provides an SDK that can be used to install AEM on your local machine for development purposes. The setup process typically includes:
- Downloading and running the AEM Quickstart JAR
- Setting up author and publish instances
- Accessing the CRXDE Lite development console
- Configuring user accounts and permissions
- Deploying content packages
A local environment allows for safe experimentation and testing. You can build simple templates, create sample components, and explore the repository without affecting production systems.
Planning for the Journey Ahead
It’s important to approach AEM learning with a clear strategy. Becoming an expert won’t happen overnight. Begin by setting learning goals and timelines. For example:
- Month 1: Focus on Java and frontend skills
- Month 2: Learn Sling and JCR concepts
- Month 3: Practice building components in a local AEM instance
- Month 4: Dive into templating, workflows, and event handling
Use this roadmap to stay focused and motivated. Keep notes, build small projects, and constantly review what you’ve learned. As you gain confidence, start identifying areas where you can go deeper, such as performance optimisation or custom integrations.
Soft Skills for a Successful AEM Career
While technical knowledge is important, soft skills are equally vital. AEM developers often work with cross-functional teams including designers, QA, content authors, and project managers. Key soft skills include:
- Clear communication, especially when explaining technical issues to non-technical stakeholders
- Collaboration and teamwork in agile or scrum environments
- Time management and prioritisation
- Willingness to learn and adapt to changing technology
These skills not only help you succeed in the workplace but also support long-term career growth.
To summarise, the AEM Sites Developer Expert journey involves building a strong technical foundation in Java, web technologies, version control, and CMS principles. AEM is a complex system that integrates many layers of technology. Only by mastering the basics can you truly understand and harness the power of the platform.
Navigating Core AEM Concepts
Once the foundational knowledge is firmly in place, the next step is to delve into the inner workings of Adobe Experience Manager (AEM). AEM is a powerful and complex content management platform built upon several interrelated technologies. Understanding how these technologies interact and how to leverage them for real-world development tasks is what transforms a proficient developer into an expert.
In this part, we explore essential AEM concepts such as Sling Models, components, templates, workflows, event handling, and how these pieces fit into the AEM architecture. Mastery of these topics is essential for delivering scalable, maintainable, and flexible AEM-based web solutions.
Exploring Sling Models
Sling Models play a crucial role in bridging the gap between Java code and HTL templates in AEM. They offer a clean and declarative way to map data from the JCR (Java Content Repository) into Java objects, which can then be used to render dynamic content.
Sling Models are typically used to:
- Bind resource properties to Java fields using annotations like @ValueMapValue
- Inject AEM-specific objects using @Self, @OSGiService, or @ScriptVariable
- Perform lightweight business logic within the model
A developer can create a model that automatically adapts to a resource or request. This adaptation allows the same model to be reused across different components, improving code reusability and maintainability. Understanding Sling Models involves learning:
- The Model annotation and adaptable types
- Injection strategies and lifecycle methods
- Exporters for exposing models to JSON, especially in headless scenarios
This is a key skill in modern AEM development, enabling the separation of logic from templates and enhancing code clarity.
Building and Managing AEM Components
Components are the building blocks of AEM pages. They represent reusable pieces of content such as text blocks, images, forms, or carousels. Developing AEM components requires a mix of backend logic (Java), templating (HTL), and frontend presentation (CSS/JavaScript).
The process includes:
- Defining a resource type and folder structure under /apps
- Creating HTL files for rendering content
- Defining dialogs using XML to enable author configuration in the editor
- Registering components in policies and templates
A good practice is to follow a modular and reusable approach, breaking down large UI blocks into smaller, focused components. Each component should:
- Be self-contained and testable
- Handle missing data gracefully
- Follow a consistent naming convention
Understanding how to work with editable and design dialogs also enhances the flexibility of components. This includes enabling authors to configure styling options or content behavior without developer involvement.
Advanced component development may also involve:
- Nested components using data-sly-resource
- Dynamic inclusion of other components
- Writing context-aware logic with Sling Models
- Managing client libraries for CSS and JS dependencies
Working with Templates in AEM
Templates define the structure of pages and dictate how content is arranged and displayed. AEM supports two primary template types: static templates and editable templates.
Static Templates are defined with fixed structures and are created by developers. These are less flexible and require code changes to update.
Editable Templates allow authors and administrators to create and manage templates through the AEM interface without writing code. They support:
- Structure layer for fixed layout and locked components
- Initial content for preconfigured elements
- Policy settings to restrict which components and styles are allowed
Learning how editable templates work is vital for building flexible and scalable AEM sites. Key elements include:
- Template types and policies
- Allowed components per container
- Responsive grid systems
- Template inheritance for design consistency
Templates promote reuse and governance, ensuring that pages adhere to branding and layout rules without sacrificing flexibility for content authors.
Introduction to HTL (HTML Template Language)
HTL is the templating language designed specifically for AEM. It replaces JSP and enables developers to write more secure and readable templates.
HTL uses special attributes and expressions to inject data and control rendering. Some common elements include:
- data-sly-use: Includes Sling Models or Java classes
- data-sly-list: Iterates over arrays or lists
- data-sly-test: Conditional rendering
- Expression language: ${} to access object properties
HTL promotes clean separation of logic and presentation, preventing the embedding of Java code within templates. It also includes automatic context-aware escaping, which helps avoid common security issues like cross-site scripting (XSS).
HTL templates work best when combined with Sling Models, enabling developers to push all business logic into Java and use HTL strictly for presentation.
Creating Authoring Dialogs
A dialog in AEM is the interface through which content authors enter or modify data for a component. There are two types of dialogs:
- Edit Dialogs: Used to manage the content of the component
- Design Dialogs: Used to control design-specific aspects such as layout, visibility, or style, generally stored in policies
Dialogs are configured using XML (Classic UI) or Granite/Coral UI components. Learning how to build effective dialogs involves:
- Defining meaningful field names and types
- Grouping fields logically
- Using multifields, dropdowns, and checkboxes
- Writing custom validators or field listeners when needed
Good dialog design empowers content authors to manage content intuitively and reduces the dependency on developers for everyday changes.
Automating Processes with Workflows
Workflows in AEM are used to automate and manage content-related processes. Examples include reviewing and approving content, publishing pages, or handling asset metadata enrichment.
A basic workflow consists of:
- A model that defines the steps and transitions
- Workflow launcher to trigger execution
- Participants such as users or groups
- Process steps which could be scripts or Java classes
Common tasks automated through workflows include:
- Content review and approval
- Scheduled publication
- Metadata extraction for digital assets
- Language translation workflows
Developers can create custom workflow steps to integrate with external systems or perform advanced tasks. Learning how to use and extend workflows provides a major advantage when working on enterprise projects that involve complex content governance and compliance requirements.
Responding to Events in AEM
AEM supports event-driven programming through OSGi event listeners and Sling event handlers. These allow developers to trigger custom logic in response to changes in the repository, such as content creation, deletion, or modification.
Event handling involves:
- Registering listeners for specific event types
- Implementing logic in Java services
- Using event filters and conditions
- Logging and managing asynchronous processing
Use cases include:
- Sending notifications when content is modified
- Invalidating caches
- Triggering reindexing or reprocessing tasks
- Logging audit trails
Understanding how to harness events within AEM provides powerful control over site behavior and can be instrumental in optimising performance and operations.
Configuring AEM Environments
Configurations are essential for managing different behaviors across environments such as development, staging, and production. AEM uses OSGi configuration systems to manage this behavior.
Each configuration is defined based on run modes. For example:
- author for author instance configurations
- publish for publish instance-specific settings
- dev, stage, prod for environment targeting
Developers manage configurations through XML or JSON files, which are deployed as part of the project. Understanding how to separate code and configuration makes deployments cleaner and environments easier to manage.
We’ve explored the core technologies and concepts that define AEM development: Sling Models, components, templates, HTL, workflows, dialogs, event handling, and configuration management. These are the foundational elements that every AEM Sites Developer Expert must master.
Each of these areas is complex and requires focused learning and hands-on practice. By building components, setting up templates, designing dialogs, automating workflows, and responding to system events, you move closer to true AEM mastery.
Gaining Hands-On Experience and Building Real-World Skills
The transition from understanding theory to becoming a proficient AEM developer occurs through consistent hands-on experience. Real-world projects help you reinforce what you’ve learned, expose gaps in knowledge, and sharpen your ability to think critically under practical constraints. By setting up your development environment, building feature-rich applications, experimenting with different AEM functionalities, and actively participating in the broader developer community, you develop the practical confidence and versatility needed to become an expert.
Setting Up a Local AEM Development Environment
Your journey begins with configuring a proper AEM environment on your local machine. Adobe provides an SDK that allows developers to run AEM in either author or publish mode. The setup involves:
- Downloading the latest AEM SDK package (Quickstart JAR)
- Running the JAR with the appropriate license and start-up commands
- Configuring JVM memory parameters and garbage collection settings
- Creating run modes (such as dev, author, publish) to simulate different environments
- Accessing the CRXDE Lite console to inspect and modify the content repository
It is important to become comfortable switching between author and publish instances, deploying packages, managing permissions, and resetting environments when needed. Automation scripts can simplify this process. As you work, learn how AEM logs and configuration files help in debugging and monitoring runtime behavior.
A local environment enables you to explore freely without impacting a shared team environment. It allows experimentation with features like workflows, asset management, replication agents, and custom services.
Building Simple AEM Projects from Scratch
Once your environment is ready, start creating a sample site. Begin with small-scale use cases and gradually evolve the complexity. A basic project could be a company homepage with components like banners, hero images, service cards, and testimonial sections. The steps include:
- Designing a basic site structure and content hierarchy
- Creating editable templates for different page types
- Building and testing reusable components with dialogs
- Using client libraries for CSS and JavaScript inclusion
- Writing Sling Models to manage content retrieval
- Linking pages through navigation components
This hands-on practice introduces you to real-world workflows. You’ll work through challenges like:
- Managing component dependencies
- Testing layout responsiveness
- Handling multilingual content
- Optimising image assets
- Securing authoring and publishing rights
Each challenge brings valuable learning that is difficult to gain through documentation alone. As the site grows, simulate more complex features such as content targeting or dynamic data loading.
Expanding Projects with Intermediate Functionality
After building and testing basic pages, it’s time to expand functionality. You can create new features that simulate enterprise-level requirements, such as:
- Custom workflows that trigger approval before page publication
- Event listeners that log changes to specific content nodes
- Personalised content based on user segments or time of day
- Integration with headless APIs using Sling Models and JSON exporters
- Asset tagging and smart search capabilities for authors
- Page version control and rollback options
Begin by automating authoring tasks. Create a workflow that alerts reviewers via email when a page is ready for approval. Customize it with decision steps and metadata updates. Then, configure launchers to initiate workflows based on content changes. This reinforces your understanding of how AEM handles tasks behind the scenes.
Add dynamic content using Sling Models to retrieve and display related articles, popular products, or time-sensitive banners. Create HTL templates that render this data cleanly, using conditional logic and loops. Test your code by deploying packages and validating content rendering in the browser.
Introduce client-side logic where needed, ensuring performance is not compromised. Understand how to group client libraries, manage dependencies, and use minification. As your project expands, build clear documentation, folder structures, and naming conventions. These practices mirror how real teams collaborate on large-scale AEM implementations.
Learning Multi-Site Management and Localization
AEM excels at managing complex digital ecosystems, including multiple websites under a single platform. One of the most advanced features is Multi-Site Management (MSM), which allows developers to manage and reuse content across different language or regional versions of a site.
Start by:
- Creating a blueprint site and several language copies
- Defining live copy relationships and rollout configurations
- Modifying structure and content in parent and child sites
- Resolving content inheritance conflicts
- Managing translation workflows and language dictionaries
Through MSM, you’ll learn how changes in a master site cascade across variants, and how to manage exceptions. Localization workflows, especially when integrated with translation tools, are important for building globally scalable content solutions.
Building multi-site and multilingual capabilities is a complex but critical skill for enterprise AEM developers. It requires technical planning, process understanding, and close collaboration with content authors.
Practising Performance Optimisation and Caching
As your AEM projects scale, performance becomes a critical concern. AEM performance tuning often begins with caching, load management, and dispatcher configuration. Gain practical experience by:
- Configuring dispatcher rules to cache HTML pages and assets
- Enabling statfiles to manage cache invalidation efficiently
- Testing how different selectors and suffixes affect cache behaviour
- Monitoring server logs for performance bottlenecks
- Setting up scheduled tasks to purge and rebuild cache automatically
Use tools to simulate traffic, such as load testing suites. Monitor how your pages perform under load, then optimise by lazy-loading components, minimising bundle size, and removing unnecessary logic from templates.
Improve back-end performance by reviewing Sling Model efficiency, reducing unnecessary queries, and simplifying logic within components. Ensure that workflows and event listeners run asynchronously when appropriate. Finally, configure loggers and monitoring tools to detect and address performance issues early.
Performance skills are often what separates intermediate developers from experts. Knowing how to tune AEM to scale under load makes your expertise highly valuable.
Engaging with the AEM Developer Community
No developer grows in isolation. Engaging with the broader AEM community accelerates learning, provides support, and connects you with people facing similar challenges. Start by joining developer forums and asking questions. Search for discussions about component best practices, project structures, and deployment issues.
Attend community events, conferences, or webinars focused on AEM development. These events often feature deep dives into new releases, architecture updates, and use-case presentations. Stay informed about trends such as headless AEM, hybrid deployments, or serverless integrations.
As you gain confidence, begin sharing your experience. This can take the form of:

- Code snippets or patterns you’ve built
- Presenting demos or tutorials internally or online
- Participating in open-source AEM plugin projects
- Contributing bug fixes or improvements to community tools
By participating, you not only grow your network but also learn to explain your ideas clearly—an essential skill for team leadership.
Practising Real Deployment and DevOps Scenarios
To become a full-stack AEM expert, you must understand deployment practices and operational configurations. AEM projects are often deployed using automated pipelines. Begin by:
- Learning how to build content and code packages using Maven
- Creating filters to ensure only the right content is deployed
- Configuring deployment profiles for different environments
- Writing scripts to back up and restore AEM instances
- Managing environment-specific OSGi configurations
Set up pipelines using CI/CD tools and deploy your project to a staging environment. Simulate version upgrades and troubleshoot configuration differences between local and remote setups.
Understand cloud deployments and provisioning. Learn how run modes affect logging, configuration, and service behavior. Read about Dispatcher tools used to filter requests, prevent unauthorized access, and serve static content from cache.
These real-world deployment scenarios complete your training. You learn how to move from a codebase to a live site responsibly, ensuring stability, security, and scalability.
This journey emphasizes hands-on experience—arguably the most important phase in becoming an AEM Sites Developer Expert. Setting up and managing a local environment, building projects from scratch, expanding with advanced features, optimizing for performance, and participating in the community bring theory to life.
Working on real scenarios allows you to internalise development concepts. Challenges encountered while deploying packages, configuring workflows, managing localization, or scaling performance force you to develop problem-solving skills that no tutorial can teach.
