About me
Need an AI chatbot, AI agent or workflow automation that actually runs in production? That is what I build.
I'm Abdul Hai, an AI and full stack engineer with 11+ years of experience. I deliver RAG chatbots on your own data, LangGraph agents with tools, n8n, Make and Zapier automations, and Next.js, Node.js and Python web apps and SaaS products. My recent work includes a multi-channel AI support agent on Claude and OpenAI that handles orders, returns and refunds with human approval and guardrails.
Every project gets a clear scope, regular updates and docs. Tell me what you want automated.
