👋 About Me

I'm Zen, a full-stack software engineer who ships complete, production-grade products — not demos. I've built and delivered 120+ projects across web, mobile, desktop, and systems domains, covering everything from database schema and row-level security policies to custom native Android runtimes and offline-first sync engines.

• 🎓 BS Information Technology — Dalubhasaan ng Lungsod ng Lucena (Graduating 2026)
• 🌏 Based in the Philippines — available for remote work worldwide
• 🔐 Background in cybersecurity (Cisco-certified) — security is in my architecture, not bolted on
• 🛠 I've shipped for real clients, real users, and active communities — not just personal portfolios
• ✅ Actively open to hire — freelance, contract, or full-time remote

I don't just build features. I architect systems that are secure, offline-resilient, and designed to scale.
