Muhamad Zein

I build web apps — and run the business that uses them.

I founded Alkompi Computer, a used-laptop store in Sleman, and I'm the developer behind its catalog, admin tools and server. I've been building with PHP, Java and MySQL since studying Informatics at UIN Sunan Kalijaga, and I like software that solves a real problem for the people using it.

Alkompi Computer

Alkompi buys, sells and services used laptops (ThinkPad, Dell Latitude, HP, Asus) in Sleman, Yogyakarta. I replaced the shop's Google Doc catalog with a website customers can browse and share, plus an admin panel the shop can run day to day.

  • Catalog search and filters for brand, budget, RAM and screen size, kept in the URL so a filtered list can be sent straight to a buyer.
  • One-tap Ask, Copy specs and Photos on every unit, because customers buy over WhatsApp.
  • Admin panel for stock, featured units and photo uploads. Photos are resized to WebP and stripped of GPS data.
  • Installable as an app (PWA) and self-hosted on a VPS, with builds that don't take the site down and a one-command rollback.
  • Next.js
  • React
  • TypeScript
  • Tailwind CSS
  • SQLite + Drizzle
  • Nginx
