About this gig
Looking for a clean, secure, and production-ready Java backend for your web or mobile app?
I build high-performance RESTful APIs, robust microservices, and database architectures using Java Spring Boot. I deliver modular, scalable code built to enterprise standards.
Whether you need a backend built from scratch, custom database integration, or JWT security added to existing endpoints, I ensure your team gets fast, fully documented APIs.
WHAT I CAN BUILD FOR YOU:
- Custom RESTful APIs: Scalable endpoints with proper HTTP status codes & error handling.
- Database Architecture: PostgreSQL or MySQL integration using Spring Data JPA & Hibernate. Auth & Security: Stateless JWT authentication & role-based Spring Security.
- API Documentation: Interactive Swagger UI & ready-to-import Postman collections.
- Clean Code: Input validation & optimized SQL database queries.
TECH STACK:
- Java, Spring Boot, Spring Security, Spring Data JPA
- PostgreSQL, MySQL, Swagger, Postman, Maven, Git

FAQ
What do you need to get started on my backend project?
A clear summary of your application flow, a list of required API endpoints, or database requirements. If you have wireframes, UI mockups, or an existing technical specification, please attach those as well.
How will my frontend or Android developer connect to this backend?
I provide full API contracts using Postman collections and/or interactive Swagger UI documentation. Your frontend/mobile developer will see every request format, header, parameters, and response structure clearly laid out.
Do you support both PostgreSQL and MySQL?
Yes! I use Spring Data JPA and Hibernate, allowing smooth entity configuration and query execution for both PostgreSQL and MySQL databases.
Can you set up secure user login and roles?
Absolutely. In the Premium package (or via custom offers), I implement stateless JWT authentication with Spring Security to lock down endpoints based on user roles (e.g., Admin vs. Standard User).
Does this package include cloud hosting and deployment?
Standard orders cover source code delivery and local setup setup/testing. If you require online deployment to platforms like AWS, Render, Railway, or Heroku, let me know in our chat for a custom deployment add-on.
