I will fix debug and optimize your langchain rag or llm app


About this gig
Built an AI app that worked on your machine but breaks the moment real users touch it? You are not alone. Most RAG and LLM apps fail on the same things: bad retrieval, hallucinated answers, slow responses, broken deployments, or vector search that returns junk.
I fix exactly that. I build production multi-agent RAG systems myself, including FinTex, a four-agent financial research system with source-cited answers, so I know where these pipelines actually break.
What I will handle:
Retrieval and chunking issues that return wrong context
Hallucinations and prompt problems
Slow or expensive API calls
Vector DB setup and tuning (Qdrant, FAISS)
Deployment and FastAPI errors
You get a working, diagnosed app plus a short note on what was wrong and how I fixed it.
Message me with your problem before ordering and I will tell you honestly if I can fix it and how long it will take.

FAQ
Which frameworks do you work with?
LangChain, LangGraph, CrewAI, LlamaIndex, plain OpenAI/Claude/Gemini API code, and vector databases like Qdrant and FAISS.
Do you need my API keys?
Only if required to reproduce the bug. You can rotate them after delivery, or I can guide you to run the fix on your side.
What if you can't fix it?
If I take the order and cannot solve it, you get a full refund. That is why I ask you to message me first.
Can you fix no-code builds (n8n, Make, Flowise)?
Yes, those count too. Send me the workflow and the error.
