About this gig

Struggling with your AI chatbot or RAG LLM application?

I will quickly debug, fix, and optimize your AI-powered mobile app, web app, or chatbot so it runs smoothly, costs less, and performs better.

As a specialized AI Software Engineer with deep experience in full-stack development, RAG systems, LLM integration (OpenAI, Grok, Anthropic, Llama, etc.), LangChain/LangGraph, vector databases, and mobile/web frameworks, I solve complex problems that many developers struggle with.


Common issues I fix fast:

  • Chatbot not responding correctly or giving hallucinations
  • High token usage and expensive API costs
  • Slow retrieval or poor RAG performance (chunking, embeddings, vector search issues)
  • Integration bugs between frontend, backend, and LLM
  • Full-stack web/mibile problems (Next.js, React, React Native, Node.js, FastAPI, etc.)


Why choose me?

  • Focused on micro-fixes fast turnaround for debugging & optimization
  • Clean, production-ready solutions with explanations
  • Experience building and maintaining real-world RAG chatbots & AI apps
  • Clear communication
