About me

Hi, I'm Michael,Full-Stack Developer

  • Web Developer
  • Systems Builder
  • IT Educator

I'm Michael, a full-stack developer and IT educator from San Carlos City, Negros Occidental. I spent two years as an IT instructor at Central Philippines State University, teaching programming, networking, data structures and information security, and now I build software for clients full time.

I build web, desktop and Android apps with Vue 3, Quasar, Node.js, Supabase and MySQL, plus fast, search-ready websites on Cloudflare. My systems run real businesses at home and abroad: a POS with payroll and biometric attendance, an inventory system with automated weighing, and a live website for a custom home builder in Florida.

I earned my BSIT from CPSU in 2024, then took Master of Information Technology coursework at SUNN. Outside client work I'm into cybersecurity and Capture the Flag challenges, which keeps me security-minded in everything I ship.

Selected work

Built for real businesses.

Systems and websites built for real businesses, most of them running every day. Each demo is a copy of the working system loaded with sample data, so you can try every screen without touching a real business's records.

    Farm Inventory System

    Built for a working farm to run its stock. Every delivery is weighed on a connected scale at intake, labelled with a barcode and QR code on the spot, and tracked live through sorting, sales and dispatch, so stock levels are always current.

Process

How we'll work together.

  1. 01

    Discuss

    We talk through what you need, who will use it and what success looks like.

  2. 02

    Plan

    I propose the screens, features and timeline, and you approve before I build.

  3. 03

    Build

    I build in stages and show you progress, so changes happen early, not at the end.

  4. 04

    Launch & Support

    I deploy it, train your team if needed, and stay on hand for fixes.

Open to freelance projects and full-time roles.
