Muhammad Nafiz — AI Agent & Automation Developer

01 — About

I turn complex workflows into simple AI systems.

For 2.5+ years I've been designing automation flows in n8n, building AI agents that handle real business work, and engineering RAG & LangChain systems with Python.

As founder of NexThynk AI, I lead a small team of 3 delivering AI agents, automation and custom AI solutions. I also built RoktoFinder — a blood donor platform serving Bangladesh.
