I will develop java or python backend API and fix bugs


Über diesen Service
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!
