Fatima Hanif
About this gig
Already paid someone who could not fix it? I will find the root cause and deliver working code with a full explanation of what went wrong.
Building AI agents taught me how they fail.Now I use that knowledge to fix yours faster than anyone who has only done one or the other.
What I Fix:
· LangChain: broken chains, tool call failures, memory loss
· LangGraph: state not persisting, node failures, routing bugs
· CrewAI agents: role conflicts, task failures
· RAG pipeline: wrong results, hallucinations, empty retrieval
· VectorDB errors: Pinecone, ChromaDB, FAISS, Weaviate, Qdrant
· LLM bugs: OpenAI, Gemini, Claude, Llama, N8N error
· MCP: servers, LangSmith tracing, n8n workflow automation bugs
· Vibe coded apps: Cursor, Bolt, Replit, Lovable, Windsurf
What You Get:
· Honest scope assessment upfront
· Full stack code review
· Your code stays private and confidential
· Progress updates throughout
· fixed code
· 2-day post-delivery support
Your agent is losing you time right now. Message me, describe the issue, and I will tell you exactly how I will fix it before you place an order.

FAQ
Do I need to share my full codebase with you?
You only need to share the relevant parts of your project — the agent code, pipeline, or specific files related to the issue. You do not need to share your entire codebase.
What if you cannot fix my issue?
Message me before ordering and I will review your issue first. If it is outside my scope or not fixable, I will tell you honestly before you spend anything.
Which AI frameworks and tools do you support?
LangChain, LangGraph, CrewAI, RAG pipelines, Pinecone, ChromaDB, FAISS, Weaviate, Qdrant, OpenAI, Gemini, Claude, Llama, Mistral, LangSmith, MCP servers, n8n, and vibe coded apps built on Cursor, Bolt, Replit, Lovable, and Windsurf.
My agent was built by another freelancer. Can you still fix it?
Yes. This is one of the most common situations I handle. I will review the full stack regardless of who built it and identify exactly what is wrong.
Is my code safe and confidential?
Completely. Your code and business logic stay private. I do not share, reuse, or retain any client code after delivery.
What do I need to provide to get started?
A description of the issue, access to the relevant code, any error messages or logs you have, and a brief explanation of what the agent is supposed to do versus what it is actually doing.
Why is your price lower than other specialists?
Because I am not charging you for meetings, project management, or unnecessary rebuilds. You have a broken system. I fix it and deliver it. That focused process keeps costs honest.
What if the same issue comes back after delivery?
If the exact same issue reoccurs within 48 hours of delivery, message me immediately. I will review it at no extra cost. A fix that breaks again the same way is not a fix.
I am not sure which package is right for me. How do I choose?
Simple rule — Basic for one clear bug, Standard for two to three connected issues, Premium if your whole agent is failing or you need frontend and backend both reviewed. Still unsure? Message me and I will recommend the right one after hearing your situation.
I have already tried fixing this myself. Why would you succeed where I failed?
Because debugging your own code is genuinely harder than debugging someone else's. You are too close to it. I come in with fresh eyes, a systematic diagnostic process, and pattern recognition built from fixing these specific frameworks repeatedly — not building them once.
