I built and deployed Pickleball World Pampanga's local-first point-of-sale and facility-management system as its sole developer, supporting approximately eight staff across Android tablets and a local mini-PC.
I developed reservation, pricing, payment, inventory, customer-balance, staff-access, reporting, backup, PDF export, and receipt-printing workflows using React, TypeScript, Capacitor, SQLite, and IndexedDB. I validated calculation-heavy features through staff interviews, field testing, manual reconciliation, production debugging, and regression testing.
At National University Clark, I co-developed a camera-free fall-detection system using ESP32-C6 devices, Wi-Fi CSI, and a quantized 1D-CNN deployed through Edge Impulse and TinyML. Our work achieved 93% validation accuracy and 0.94 F1, and the team received Best Paper and Best Presenter recognition at IRC-CPE 2026.
I also build practical web applications, including ReClaim, an AI-powered lost-and-found system, and SpriteLEE, a browser-based pixel-art and sprite editor.
