Khan
About this gig
Need a secure, scalable, and lightning-fast backend for your web or mobile application?
I specialize in building enterprise-grade REST APIs and microservices using Java Spring Boot. My approach is rooted in deep architectural understanding and algorithmic efficiency, ensuring your endpoints don't just workthey resolve in milliseconds and scale effortlessly under load.
What I offer in this gig:
- RESTful API Development: Clean, well-documented endpoints (GET, POST, PUT, DELETE).
- Database Integration: Seamless mapping using Spring Data JPA / Hibernate (MySQL, PostgreSQL, etc.).
- Robust Security: Implementation of Spring Security with JWT (JSON Web Tokens) or role-based access control.
- Refactoring & Optimization: Upgrading legacy code, optimizing database queries, and resolving stubborn dependency conflicts.
- Clean Architecture: Strict adherence to layered architecture (Controllers, Services, Repositories, DTOs).
Whether you need a standalone microservice or a complete backend from scratch, I write highly maintainable, production-ready code.
Please message me before placing an order so we can discuss your exact technical requirements and database schema!

FAQ
Do you provide API documentation?
Yes. I highly recommend using Swagger/OpenAPI. I can configure SpringDoc in your project so you have a beautiful, interactive interface to test all endpoints upon delivery.
Can you secure my APIs so only logged-in users can access them?
Absolutely. For the Premium package (or as a custom extra), I implement Spring Security utilizing stateless JWT authentication, ensuring your endpoints are completely protected.
What databases do you work with?
I primarily work with relational databases like MySQL and PostgreSQL. I handle all the underlying entity mapping and repository logic using Spring Data JPA.
Do you deploy the application to a live server?
This gig focuses strictly on backend code delivery and local testing. However, if you need a compiled .jar file or a Dockerfile for containerized deployment, let me know in our initial message.This gig focuses strictly on backend code delivery and local testing.
