I will build an ai powered rest API using python and fastapi


About this gig
Need a clean, production-ready backend or AI-powered API for your product or MVP?
I build scalable REST APIs and AI-integrated backends using FastAPI and Python. I've built and deployed multiple backend systems including an e-commerce API, a blog platform, and an AI-powered content distribution backend (Scaterly) covering authentication, user management, third-party integrations, and LLM integration.
What I Build:
- REST APIs for web apps, SaaS, or mobile backends
- JWT Authentication secure login, registration, protected routes
- Database integration (PostgreSQL, MySQL, Supabase)
- Full CRUD systems with clean business logic
- AI/LLM integration (OpenAI, Gemini, LangChain)
- RAG-based chatbots and document Q&A systems
- Pydantic validation and error handling
- Deployment on Render or Railway
What You Get:
- Clean, maintainable code not quick fixes
- Proper project structure used in production systems
- Security best practices and env-based config
- Fully commented code for easy handoff
- Postman collection for testing
- Clear communication throughout
Why Me?
I build backends that are readable, scalable, and easy to maintain clean structure, proper validation, and security from day one. Whether you need a pur

FAQ
Do you work with any tech stack or only FastAPI/Python?
I specialize in FastAPI and Python as my core stack. If your project uses a different framework, feel free to message me before ordering — I'll let you know if I can help.
Can you integrate AI features like ChatGPT into my existing backend?
Yes, I can integrate OpenAI, Gemini, or LangChain into your existing backend or build a new AI-powered API from scratch depending on your requirement.
Will I own the source code after delivery?
Absolutely. You get full ownership of the source code, project files, and Postman collection. No strings attached.
What if I need changes after delivery?
Revisions are included based on your package (Basic: 1, Standard: 2, Premium: 3). I also make sure to clarify all requirements before starting so revisions are minimal.
Can you deploy the API so it's live and accessible?
Yes — deployment on Railway or Render is included in the Premium package. For Basic and Standard, I provide the full codebase ready to deploy with clear instructions.
