About this gig
Is your RAG chatbot returning irrelevant answers, ignoring documents, losing conversation memory, or failing to retrieve the correct data?
I will diagnose and fix errors in your LangChain, LangGraph, RAG pipeline, embeddings, retriever, vector database, API integrations, and AI-agent workflows. Ill identify the root cause and improve retrieval quality, response accuracy, stability, and performance.

Incorrect or irrelevant RAG responses
Documents not being retrieved
LangChain chain and agent errors
LangGraph state and routing issues
Vector database connection errors
Pinecone, Supabase, Weaviate, Chroma or Qdrant
Embedding and dimension mismatches
Chunking and document-loading problems
Metadata filtering issues
Conversation memory errors
Duplicate or outdated vectors
API, webhook and authentication failures
Slow retrieval and response times

Message me before ordering with your error details, architecture, logs and expected result so I can recommend the correct fix.
