I will fix bugs in your ai agent, chatbot, rag or langgraph application
Muhammad Irfan
About this gig
Your AI agent loops, your chatbot gives wrong answers, or your RAG app can't find the right document? I find the root cause and fix it in your existing code.
What I can fix
- LangGraph and LangChain agents and MCP tools: state, routing, tool calling and memory issues
- RAG problems: chunking, embeddings, vector search (Pinecone, Chroma, FAISS, Qdrant) and weak retrieval
- OpenAI, Claude and Gemini API errors, timeouts and rate limits
- Prompt and structured-output issues that cause wrong or broken answers
- n8n workflow errors
- FastAPI backend bugs and Docker or deployment failures
How I work
- You share the repo or workflow and the exact problem
- I reproduce it and trace it to the cause
- I fix it, test it and explain what was wrong and what changed
I build production AI agents and RAG systems myself, backed by 6+ years of full stack engineering, so I debug the whole stack, not just the prompt.
Please message me before ordering so I can confirm the issue fits the package.
