You will get you will get your AI chatbot or agent debugged, fixed and optimized
Rising Talent
Project details
Your AI chatbot is live but something is wrong. It's hallucinating, giving off-topic answers, too slow, timing out, or costing way too much in API calls. You don't need someone to rebuild it from scratch you need someone who can diagnose what's broken and fix it fast.
What I fix:
• Hallucinations and wrong answers prompt engineering and retrieval fixes
• Slow or timing out responses async handling, streaming, caching
• High API costs token optimization, model routing, chunking strategy
• Broken context and memory conversation history architecture
• RAG retrieval failures reranking, chunk size, embedding model tuning
• LangChain or LlamaIndex pipeline errors chain debugging, tool call failures
• OpenAI, Claude, Gemini API errors rate limits, timeout handling, fallbacks
• n8n or Make.com AI workflow failures node debugging and restructuring
• Agent loops and stuck reasoning stop conditions and tool call fixes
How it works: share your codebase or describe the issue. I diagnose within 24 hours and deliver within the window. You get a written explanation of what was wrong not just a fixed file.
If I assess your issue and genuinely cannot fix it, I will tell you before any work begins.
