About this gig

Need a backend that actually works in production not just 

a tutorial copy-paste? I build FastAPI backends that are 

clean, documented, and ready to scale.


What I build:

REST APIs with proper auth (JWT, API keys, OAuth)

Backends that connect to OpenAI, Claude, or any LLM

RAG pipelines upload documents, query them with AI

Database integration (PostgreSQL, Supabase, SQLite)

Deployed and live on Railway, Render, or Hugging Face


Real proof: TRIDENT is a FastAPI system I built that 

accepts PDF uploads, extracts requirements using AI, runs 

RAG-based compliance checks, scores proposals on 4 factors, 

and returns a finished proposal all through a single API. 

PHANTOM's AI service layer runs as a FastAPI backend 

deployed and serving live requests.


What you get:

Full source code, yours to own and modify

Auto-generated API docs (Swagger/OpenAPI included)

Proper error handling not code that breaks in prod

Clear readme so your frontend team can integrate it
