About this gig

Need a reliable Java backend for your web or mobile app? I build clean, scalable REST APIs and microservices using Java 17, Spring Boot, Spring Security, JPA/Hibernate and PostgreSQL.


What you get:

  • Well-structured REST API endpoints with full CRUD
  • - Secure authentication (JWT / role-based access)
  • - PostgreSQL database design and integration
  • - Input validation, clean error handling and documented code
  • - JUnit-tested service logic

I focus on performance too. On a recent project I cut API response time by around 65% through query optimization and N+1 elimination. Whether you are starting from scratch, need an API integrated, or want an existing Spring Boot app improved, I deliver production-ready, maintainable code on time.


Please message me before ordering so I can understand your requirements and recommend the right package. Let's build something solid.
