Backend Development

$16/hr Starting at $26

Are you looking for a secure, scalable, and high-performance backend for your application? I specialize in building robust RESTful APIs using Java and Spring Boot, focusing on clean architecture and long-term maintainability.

Whether you need a new system from scratch or need to fix/upgrade an existing one, I deliver code that is easy to test, document, and scale.

What I can do for you:

  • API Design & Development: Custom RESTful APIs tailored to your business logic.

  • Security Implementation: Secure authentication and authorization using JWT (JSON Web Tokens) and Spring Security.

  • Database Management: Efficient modeling and integration with PostgreSQL, MySQL, or MongoDB.

  • Documentation: Clear API documentation using Swagger/OpenAPI so your frontend team can work easily.

  • Bug Fixing & Optimization: Performance tuning and refactoring of legacy Java code.


My Tech Stack:

  • Language: Java (17+)

  • Framework: Spring Boot (Data, Security, Web)

  • Tools: Docker, Git, Maven/Gradle

  • Architecture: MVC, Layered Architecture, DDD concepts.


Let's build a solid foundation for your project!
