I will fix, debug, or optimize your python rag and vector search pipeline


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.

FAQ
What frameworks and vector databases do you support?
I specialize in Python-based architectures using LangChain, LlamaIndex, Pinecone, ChromaDB, FAISS, and FastAPI.
How fast can you diagnose and fix my script?
Minor bug fixes and pipeline optimizations are delivered within 24 to 48 hours once access is provided.
What if the bug is caused by a third-party API outage?
I will isolate the root cause, provide diagnostic logs proving the external failure, and implement retry logic and graceful error-handling fallbacks.
Do you need access to my entire proprietary codebase?
No. You can provide an isolated reproduction script containing the pipeline logic, sample input data, and the specific error trace.
What happens if the delivered fix does not resolve the issue?
Revisions are included to ensure the delivered fix works under your verified environment specs.
