I build software that runs reliably and fix hardware with my hands. I focus on direct, practical solutions.

Detail-oriented Information Technology graduate (Summa Cum Laude, GWA < 1.20) with hands-on experience leading development on production web and mobile systems for real clients. I architect GPS-tracked mobile apps, secure QR/2FA web platforms, and multi-tenant portals using Flutter, PHP, Next.js, and MySQL.

During my 480-hour internship at IMERGEX (Mar–May 2026), I served as Lead Developer across five production systems — owning hosting, deployment, and maintenance — spanning PHP/MySQL, Next.js/Supabase, and Flutter, using AI-assisted tooling for rapid prototyping where applicable.

Beyond software, I have worked as an independent freelance PC technician since 2022. I handle hardware diagnostics, system rebuilds, thermal repasting, custom PC builds, OS recovery, and malware remediation directly for clients.
