Selected software projects and experiments.
A web app I built to navigate Fremd High School across both floors. It supports fuzzy room search, cross-floor routing, nearby restroom lookup, and turn-by-turn directions. I built A* routing over a wall-aware visibility graph with configurable edge penalties. Graph construction runs in a Web Worker; route searches run on the main thread.
A collaborative whiteboard I built for drawing and note-taking across devices. It supports real-time drawing and cursors, offline changes that replay after reconnecting, and automatic shape detection. The app uses a Node/Express backend, Socket.IO for synchronization, and PostgreSQL for persistence.
A native Android app that helps students find classrooms at Fremd High School, with floor-aware routes and search-first navigation. Built in Kotlin with Jetpack Compose.
A small userscript that removes Tabroom follow buttons to reduce accidental follows. Distributed as a single JavaScript userscript.
