I will develop spring boot apis and fix backend bugs
Jim Jiang
About this gig
Hi there! I am an experienced Backend Developer with over 15 years of software development experience, specializing in Java and Spring Boot.
If you are building a new web application, need robust RESTful APIs, or are stuck with stubborn backend bugs and database issues, I am here to help you get it done cleanly and efficiently.
What I Can Do For You:
- RESTful API Development: Design and build secure, scalable, and clean REST APIs using Spring Boot.
- Backend Bug Fixing: Diagnose and debug exceptions, performance bottlenecks, concurrency issues, and logic errors.
- Database Integration: Connect your app with MySQL, PostgreSQL, or MongoDB using Spring Data JPA / MyBatis.
- Third-Party Integration: Integrate payment gateways (Stripe, PayPal), social logins, or external REST APIs.
- Docker & Linux Deployment: Deploy your Spring Boot app to AWS, DigitalOcean, or any Linux VPS with Docker or Nginx.
Why Choose Me?
- Solid Experience: 15+ years in software engineering. I write clean, maintainable, and well-structured code.
- Full-Stack Vision: As a developer who also knows Vue/Frontend and Linux server operations, I understand how the backend connects with the real world.
- Clear Communication: No fluff.
