About this gig

Looking for a reliable backend developer to build robust APIs, design clean databases, or fix complex bugs? You are in the right place.

I specialize in building scalable, production-grade backends using Java (Spring Boot) and Python, paired with optimized relational database schemas in PostgreSQL, MySQL, and SQL Server.

What I Can Do For You:

  • Custom REST API design and full CRUD integration
  • Spring Boot microservices, Spring Security, and JWT authentication
  • Python automation scripts, data processing, and FastAPI/Flask endpoints
  • SQL query optimization, complex indexing, joins, and schema migrations
  • Cloud containerization and production deployment (Render, AWS, Docker)
  • Troubleshooting 500/404 server errors, CORS issues, and database connection bugs

Why Work With Me?

  • Production Experience: Architected and deployed live, active platforms with real-world authentication and high-availability operations consoles.
  • Clean Architecture: Maintainable, modular code with comprehensive inline comments.
  • Fast Turnaround & Clear Communication: Quick responses and full support throughout delivery.
