About this gig

I'm a backend software engineer with 1.8+ years of experience building and maintaining production REST APIs on a live legal-tech SaaS platform. I can design, build, and secure your backend from scratch or improve an existing one.


What I can do for you:

  • Design and build REST APIs using Java & Spring Boot
  • Implement authentication/authorization with Spring Security (JWT, role-based access)
  • Design relational database schemas (MySQL/PostgreSQL) and optimize slow queries
  • Integrate third-party APIs and internal microservices
  • Document APIs with Swagger and test with Postman
  • Debug production issues and perform root cause analysis


Tech stack: Java, Spring Boot, Spring Security, MySQL, PostgreSQL, DynamoDB, Docker, Git, AWS basics.


Message me before ordering with your project requirements so I can scope it accurately.
