I will fix your broken python, langchain, or rag pipeline


About this gig
Your RAG bot hallucinating? LangChain pipeline throwing errors? Vector search returning garbage? I fix it.
I am an AI/ML engineer who builds production RAG and ML systems: LangChain orchestration, FAISS and ChromaDB indexing, chunking and tokenization pipelines, FastAPI deployment, and MLflow-tracked reproducibility. I debug Python ML pipelines daily, so your broken code is a fast read for me.
What you get:
- Diagnosis of the exact failure point: retrieval, chunking, embeddings, or prompt
- Fixed, tested code with comments explaining every change
- A short video walkthrough so you understand the fix
- A written root-cause note so it never breaks the same way again
Why me:
- Production track record: FastAPI inference benchmarked at 7.4ms p95, MLflow runs pinned to git commits
- Enterprise RAG engine on LangChain + FAISS/ChromaDB grounding LLMs in private documents
- Headless async ingestion pipelines with zero third-party scraper dependencies
How it works:
- You send the error log or repo access plus expected vs actual output
- I diagnose and confirm scope within 12 hours
- Fix delivered with comments, docs, and walkthrough
If I cannot fix it, you do not pay. Message me before ordering so we scope it.

FAQ
What do you need from me to start?
Your error log or repo access, plus one line on what the pipeline should output versus what it outputs now. That is all.
What if you cannot fix it?
You do not pay. I only charge for delivered fixes. If diagnosis shows the codebase needs a full rebuild, I will say so honestly and quote the Premium package instead of burning your budget.
Is my code kept confidential?
Yes. I work inside your private repo or private snippets only. Client code is never reused, shared, or shown in my portfolio.
