Muhammad Hafi. Full-stack developer and founder of Havlen: web, desktop, Android, backend and AI, end to end. 01 About

I'm a Computer Science student at UET Taxila and a freelance developer who builds whole products, from the interface down to the protocol. I like software that has to survive the real world: no internet, an old Windows PC, a printer that only speaks USB, and a customer who will hold a ruler against the result.

  • Founder — Havlen, an AI receptionist that answers customers on WhatsApp and the web in English or Roman Urdu, books real appointments and hands over to staff when it should
  • Now — building an AI-in-the-loop data pipeline for AICON'26 at NUST (Next.js, TypeScript, Gemini)
  • Usually — web apps, Electron desktop apps, Android apps in Kotlin, and the Python and Node.js backends behind them
  • How I build — vibe coding with AI agents, then testing in the real world until it holds up
  • Care about — privacy by default, and getting it right to the millimetre
02 Selected work

Havlen, my startup: an AI receptionist for WhatsApp and the web that replies in English or Roman Urdu and books real appointments. Print Bridge: share a USB printer and its scanner with every phone in the house. Python, IPP, eSCL, Bonjour. GPS Alarm on Google Play: a location alarm that wakes you before your stop, even offline. Duplex: both sides of an ID card on one sheet at exact size, lined up back to back. QuickPrint: photo sheets for print shops at true physical size. Electron, offline.

Have an app, a printer or a pipeline that won't behave? I'd like to hear about it.
