About this gig

Facing hallucinations, broken chunking, or slow retrieval in your AI pipeline? I will debug, repair, and optimize your Python RAG architecture.


As an AI integration engineer, I resolve pipeline breakages that cause models to fail in production. Whether your vector index returns irrelevant context or your LangChain execution crashes under concurrency, I provide clean, modular fixes with test cases.


WHAT I FIX:

Vector DB connection, embedding dimension, and indexing mismatches (Pinecone, ChromaDB)

Token chunking errors, sliding-window chunk boundaries, and metadata loss

LangChain and LlamaIndex pipeline exceptions and timeout errors

High latency: optimize similarity search, reranking, and payload caching


HOW WE WORK:

1. Share your code repository or script and sample data.

2. I diagnose the bottleneck and issue a technical triage summary.

3. I deliver the corrected code with clear inline explanations and a test run script.


WHAT IS OUT OF SCOPE:

Greenfield software development and UI design (see my other custom RAG and SaaS gigs).


Message me with your error trace before ordering for a fast assessment.

Struggling with AI chatbots that hallucinate or leak sensitive company data? I build private, custom RAG pipelines and intelligent assistants grounded strictly in your business documents and APIs. Using Python, LangChain, Pinecone, and FastAPI, I engineer low-latency vector search and source-attributed responses. Proven by RepoRAG: an automated codebase assistant delivering sub-second semantic retrieval across complex repositories. You get clean, production-ready code and direct communication.
