I will build scalable fastapi backend systems with API integration and ai agents


About this gig
You have the vision (and maybe the frontend), but you need a backend that can actually handle the traffic.
Whether you are building a standard SaaS platform or a complex AI application, the foundation is the same: you need a secure, scalable, and fast API.
I am a backend developer who specializes in FastAPI. I build systems that are ready for the real world, from standard RESTful services to advanced AI integrations.
What I can build for you:
- Custom REST APIs: I design efficient, well-structured APIs. This includes CRUD operations, complex database queries, and secure user authentication (JWT/OAuth2).
- Database Design: I architect clean, normalized schemas using PostgreSQL or Supabase to ensure your data is organized and fast to retrieve.
- AI & RAG Integrations: If your project needs intelligence, I build stateful AI Agents using LangGraph and RAG pipelines to connect LLMs with your private data.
- Production Ready: I do not leave you with a "works on my machine" problem. I use Docker to ensure your backend runs perfectly on the cloud (Render/AWS).
Why work with me? I care about clean architecture. You will get code that is easy to read, easy to maintain, and easy to scale.

FAQ
Do you provide the API keys for OpenAI/LLMs?
No, you must provide your own API keys. I will build the system to use your keys securely (usually via environment variables), so you retain full control and ownership of your usage billing.
I don't need AI, just a standard REST API for my app. Can you do that?
Absolutely. A large part of my work involves building standard, high-performance REST APIs for e-commerce, SaaS, and mobile apps. I focus on clean database design and secure authentication.
Will you help me deploy the backend?
Yes! The Premium package includes full deployment support. For other packages, I provide the source code and a Dockerfile. If you need help deploying to platforms like Render, Railway, or AWS, please add the "Deployment" extra to your order.
