About this gig
Looking to build a full stack web application or MVP?
I can help you develop a complete web app with a strong FastAPI backend and clean frontend integration.
What I can do:
- Build REST APIs with FastAPI
- Design and integrate databases (PostgreSQL)
- Implement authentication (JWT, role-based access)
- Develop backend logic for users, products, orders, etc.
- Connect backend with frontend or admin panels
- Integrate third-party APIs (AI, external services)
I focus on building clean, scalable, and well-structured backend systems that are easy to extend as your project grows.
Ive also worked on my own backend and AI-related projects, so I understand real-world development flow and practical system design.
For more complex systems (payments, large-scale infrastructure, etc.), Im happy to collaborate as part of a team to ensure everything runs smoothly.
If you're not sure about your project scope, feel free to message me Id be happy to discuss and help you plat out
