I will fix, debug and optimize your langchain, langgraph or rag ai app
Kargos
About this gig
Stuck on a LangChain error, a LangGraph agent that loops forever, or a RAG chatbot giving wrong answers? I will find the root cause and fix it fast.
Problems I fix:
- Import and deprecation errors after LangChain or LangGraph version upgrades
- Agents stuck in loops, failing tool calls or broken state and memory
- RAG apps with poor retrieval (chunking, embeddings, vector store, prompts)
- Slow responses and high token costs
- OpenAI, Claude or open-source LLM integration and API errors
- Deployment errors when moving from notebook to production
What you get:
- Working, tested code with the fix applied
- A short note explaining the root cause and what changed
- Tips to stop the issue from coming back
Why me:
I build production AI agents with LangChain and LangGraph, including a 5-agent system in a Fortune 500 environment. I know where these apps usually break.
How it works:
- Send your code and the full error message
- I reproduce the issue and fix it
- You get the fixed code and a summary
Message me with your error before ordering and I will tell you which package fits.

FAQ
What do you need from me to start?
Your code (GitHub repo, zip or files), the full error message or logs, how you run it, and your Python and LangChain versions. Please use test API keys, never production passwords.
Can you fix errors after upgrading LangChain?
Yes. Version upgrades often break imports, chains and agent APIs. I update your code to current LangChain and LangGraph versions and keep the behavior the same.
My RAG chatbot gives wrong answers. Can you help?
Yes. I check chunking, embeddings, retriever settings, prompts and vector store setup, then compare answers before and after the fix.
What if the issue is bigger than the package?
Message me before ordering so I can review it. If I find more work during the order, I explain it first and suggest the right option before doing anything extra.
How fast can you fix it?
Most single errors are fixed within 1 day with the Quick Fix package. Bigger debugging or optimization work takes 2 to 4 days depending on the package.
