About this gig

I will develop clean, scalable and maintainable Java Spring Boot REST APIs for your web, mobile, or business application.

With extensive experience in Java backend development, I can build new APIs, enhance existing Spring Boot applications, integrate databases, implement authentication, and fix backend issues.

What I can provide

  • Spring Boot REST APIs
  • CRUD & business APIs
  • PostgreSQL / MySQL integration
  • Spring Data JPA & Hibernate
  • JWT authentication & authorization
  • Input validation & exception handling
  • Swagger / OpenAPI documentation
  • JUnit 5 & Mockito tests
  • Maven / Gradle configuration
  • Docker configuration
  • Third-party API integration

Development approach:

I focus on clean architecture, reusable code, proper error handling, security, maintainability and testability.

Package pricing is for clearly defined API development tasks. Complex business logic, large existing-codebase changes, Kafka, Redis, AWS deployment, microservices architecture, payment integrations, or other advanced requirements may require a custom offer.

With 9 years of software development experience, I've built and worked on production-grade backend systems, handled complex bugs, and solved issues that don't show up until systems are under real load. Based in India, working remotely with global teams — open to full-time or contract roles with companies across the US, Europe, and APAC. I specialize in Java (8+), Spring Boot, Hibernate, Kafka/AMQ, JPA, JUnit 5, Mockito, and microservices. My work goes beyond writing clean code — I focus on building systems that are reliable, scalable, and behave correctly in production.
