Portfolio
Web apps, mobile apps, browser extensions, and infrastructure — everything I've built across screens.
Campus Room & Class Finder
A SvelteKit progressive web app that helps UPLB students locate classes and rooms across campus. Features advanced filters, schedules, interactive building info, OpenStreetMap directions, and full offline support.
Grade Simulator & Forecaster
A cross-browser extension that simulates and forecasts course grades from quizzes, exams, and weighted components. Supports the University of the Philippines grading system with semantic-release versioning and a standalone landing page.
POS Terminal App with Hardware Integration
A React Native + TypeScript mobile application designed for POS machines used in bus ticketing. Includes hardware device integration, comprehensive Jest test suites, and a GitHub Actions pipeline that builds production Android APKs automatically.
Minecraft Server Infrastructure
A survival Minecraft server I founded at age 13 — managed bare-metal and cloud servers, configured Java plugins, Docker containers, and built a multiplayer community that served as a safe space for 10,000+ players over 6 years, including through the pandemic.
Astronomy Photo Diary
A Next.js astronomy diary that maps the sky above me each day — a quiet, meditative web project blending photography with technology. Built with TypeScript and deployed on Vercel.
