Java Full Stack Developer

Roles and responsibilities

A Java Full Stack Developer is a software developer proficient in both front-end and back-end development, primarily using Java for server-side programming. They have the skills to design, develop, and manage applications that encompass both the client-side (user interface) and server-side (business logic, databases, and APIs). Here's a breakdown of their responsibilities and expertise:

• Front-End Development:
  • Technologies: HTML, CSS, JavaScript, frameworks like Angular, React, or Vue.js.
  • Tasks: Building user interfaces, ensuring responsiveness, designing user experiences, and integrating front-end with back-end services.
• Back-End Development:
  • Core Language: Java.
  • Frameworks: Spring, Spring Boot, Hibernate, or similar.
  • Tasks: Developing APIs, handling business logic, data processing, and managing the application’s overall functionality.
• Database Management:
  • Skills: SQL, NoSQL (e.g., MongoDB), database design, and optimization.
  • Tasks: Creating, managing, and querying databases, ensuring data integrity, and handling migrations.
• Version Control and Deployment:
  • Tools: Git, GitHub, CI/CD pipelines.
  • Tasks: Managing code versioning, merging codebases, and automating deployments to different environments.
• Server and API Management:
  • Skills: RESTful APIs, SOAP, handling HTTP requests, server-side configuration.
  • Tasks: Setting up servers, managing security and authentication (e.g., JWT, OAuth), and optimizing for performance.
• Cloud and DevOps:
  • Knowledge: AWS, Docker, Kubernetes (optional but increasingly expected).
  • Tasks: Deploying applications to cloud platforms, using containers for scalable deployments, and managing microservices architecture.

Essential Skills

• Java (Core and Advanced).
• JavaScript/TypeScript for front-end logic.
• Spring/Spring Boot for building enterprise-grade applications.
• HTML/CSS/ReactJS for front-end design.
• Database (SQL/NoSQL) proficiency.
• RESTful APIs development and consumption.
• Version control tools (like Git).
  

Other Desirable Skills

• Microservices Architecture.
• Agile methodologies for team-based projects.
• Problem-solving and debugging expertise.

Desired candidate profile

1. Front-End Development Skills

• HTML/CSS: Proficiency in HTML5 for structuring web pages and CSS3 for styling. Understanding of responsive web design to ensure websites function on all devices.
• JavaScript: Strong knowledge of JavaScript to create dynamic and interactive web applications. Familiarity with ES6+ features (e.g., arrow functions, promises, async/await) is important.
• Front-End Frameworks: Experience with modern front-end frameworks and libraries such as:
  • Angular: A popular framework for building dynamic, single-page applications (SPAs).
  • React: A widely used JavaScript library for building user interfaces.
  • Vue.js: Another modern framework for developing web applications with a focus on simplicity and flexibility.
• CSS Preprocessors: Experience with preprocessors like Sass or LESS to make writing CSS more efficient.
• UI/UX Design Principles: Knowledge of user interface (UI) and user experience (UX) principles to create intuitive, user-friendly applications.

2. Back-End Development Skills

• Java: Expertise in Java programming language, including core concepts like object-oriented programming (OOP), data structures, algorithms, and concurrency.
• Java Frameworks: Familiarity with back-end Java frameworks such as:
  • Spring Framework (Spring Boot, Spring MVC): Popular for building scalable and efficient enterprise applications.
  • Hibernate: Knowledge of Hibernate ORM (Object-Relational Mapping) for interacting with relational databases.
  • JPA (Java Persistence API): Understanding of JPA for data persistence in Java applications.
  • Spring Security: Implementing security features in Java applications, such as authentication, authorization, and secure communication.
  • Spring Cloud: Knowledge of building microservices using Spring Cloud and related technologies.
• RESTful APIs: Experience in designing and consuming RESTful APIs, handling HTTP requests, and ensuring proper API documentation (e.g., using Swagger).
• Web Servers: Familiarity with deploying Java applications to web servers like Apache Tomcat, Jetty, or Jboss.

3. Database Skills

• Relational Databases: Proficiency with SQL and relational databases such as MySQL, PostgreSQL, or Oracle for data storage, querying, and optimization.
• NoSQL Databases: Experience with NoSQL databases like MongoDB or Cassandra, which are commonly used for handling unstructured data.
• Database Design: Ability to design database schemas, normalize data, and create efficient queries.
• ORM Tools: Familiarity with Object-Relational Mapping (ORM) frameworks like Hibernate for integrating Java applications with databases.

4. Version Control and DevOps

• Git: Proficiency with Git for version control, including branching, merging, and working with remote repositories (e.g., GitHub, GitLab, Bitbucket).
• CI/CD: Knowledge of Continuous Integration/Continuous Deployment (CI/CD) pipelines to automate the building, testing, and deployment of Java applications (e.g., using Jenkins, GitLab CI, CircleCI).
• Containerization: Familiarity with Docker for containerizing applications and deploying them across different environments.
• Cloud Platforms: Experience with cloud platforms like AWS, Azure, or Google Cloud Platform for deploying Java applications in scalable environments.
