What You're Buying
You've been stuck wiring LangChain + FastAPI for weeks. You know the stack, you just haven't shipped it. Instead of another tutorial, get a working RAG backend delivered to your GitHub in 7 days.
No back-and-forth. No discovery calls. No "let's start with a kickoff." One scoped deliverable, shipped fast.
- —A RAG pipeline that ingests your data and answers questions about it
- —FastAPI endpoints with JWT auth — register, login, protected routes
- —Server-Sent Events for real-time streaming responses
- —Docker + docker-compose, deployable to Railway or Render in 15 minutes
- —Full source code — MIT license, fork it, keep it, modify it
The Full Stack
LangChain LCEL RAG Chain
Document ingestion, chunking, embedding, vector storage (ChromaDB), retrieval, and generation wired into a production chain.
FastAPI Backend
Clean async/await architecture. Health check, chat endpoint, auth endpoints — structured for production from day one.
JWT Authentication
Access + refresh tokens, bcrypt password hashing, middleware-protected routes. The auth layer is done right.
Streaming Responses
Server-Sent Events. Real-time token streaming integrated with any LLM provider. No WebSockets, no polling.
Docker + Railway Deploy
Dockerfile + docker-compose included. Railway 1-click deploy config. Render alternative docs. Live in 15 minutes of receiving credentials.
Source Code — MIT License
Full codebase delivered to your GitHub. Use it forever, fork it, build on it. No strings attached.
What's Included — Fixed Scope
Scope is locked. No surprises, no change orders, no "we need another week."

Who Am I
Built the LangChain + FastAPI Starter Kit over 22 days. Learned that indie devs don't buy boilerplate — they buy "done for me." I'm the builder. I write the code, I deploy it, I hand you the keys. No VA, no handoff, no mystery.
