About this gig

Hi! I'm Smith, a backend developer with 10 years of experience in Java and Python.


Whether you need a quick bug fix or a complete backend system, I can help. I specialize in Spring Boot, FastAPI, microservices, and database design.


What I offer:

- Fix backend bugs in Java or Python projects

- Develop REST APIs with clean, documented code

- Database integration (MySQL, PostgreSQL, Redis)

- Docker deployment support

- Code review and optimization


I work part-time with flexible scheduling, perfect for small to medium tasks that need expert attention without a full-time hire.


Before ordering, please send me a message with your project details so I can confirm the scope and recommend the right package.


Let's get your backend running smoothly!
