About this gig

Need a clean, secure, and production-ready backend API? You're in the right place.

I'm a Java backend developer with hands-on experience building and deploying real-world Spring Boot applications. My projects are live not just on GitHub.

What I'll build for you:

  • REST API with proper layered architecture (Controller Service Repository)
  • JWT-based authentication (Register / Login / Secure endpoints)
  • PostgreSQL database with JPA/Hibernate entities
  • Exception handling with meaningful error responses
  • Clean, well-commented code with a README
  • Postman collection so you can test everything immediately

My tech stack:

Java Spring Boot Spring Security JWT PostgreSQL JPA/Hibernate Docker (Standard & Premium)

Why choose me:

I've built and deployed this exact stack in real projects

You get source code + README + Postman collection

I respond fast and communicate clearly throughout

Unlimited revisions on bugs I introduce

Not sure what you need? Message me before ordering I'll tell you honestly if I can help.

I'm a backend developer specializing in Java and Spring Boot, with hands-on experience building and deploying real-world applications. I've built a Real-Time Job Alert System (WebSocket + Redis + PostgreSQL, live at Vercel), an AI Career Coach (FastAPI + Groq + MongoDB), and an AI-powered GitHub repo assistant using RAG. My projects aren't just code — they're deployed and working. I work with Java, Spring Boot, PostgreSQL, Redis, Docker, WebSocket, JWT, Python, FastAPI, and Spring AI. If you need a reliable backend built clean and fast, let's talk.
