Hi, I'm Jamaica Magbanua. I specialize in full-stack web development, offline-first mobile applications, and software security. I turn complex problems into elegant, scalable solutions.
Building responsive, data-driven systems with a focus on seamless UX and robust backend logic.
Cross-platform and standalone apps.
MySQL • SQLite • Drift
SAST • Vulnerability Detection
Systems, tools, and applications I've built.
"Keep It Simple and Secure" performs real-time static security analysis (SAST) for PHP code, identifying vulnerabilities like XSS and SQL injection right in the editor.
Offline-first mobile bookkeeping app with complex accounting logic handling double-entry systems, depreciation, and contra-asset accounts.
Flood Stream (FloS) is a data-driven flood control monitoring system featuring an interactive GeoJSON map, data visualization, and public feedback routing.
QR-based attendance system automating tracking, automated scoring, and CSV data export.
Inventory and POS system with Google login integration and offline selling registers.
Simplifies logic using Quine–McCluskey method. Demonstrates tokenization and binary trees.
Led the student organization, mentored peers in development workflows, and managed collaborative technical projects.
Competed and placed consistently for three consecutive years in the regional cybersecurity and development hackathon.
Presented the FloS data-driven flood control monitoring system at the regional Data Festival.
A visual record of my continuous learning, workshop participation, and competitive achievements.
