Projects

Built for a friend to turn Ultimate Guitar tabs into clean, printable PDFs — with controls for font, spacing, transposition, and autoscroll.

An AI-powered web platform for physical therapy providers to track and analyze patients' range of motion (ROM) over time. Leverages OpenCV and MediaPipe for real-time pose analysis via websockets, with Firebase for secure data storage and LLM-powered insights. Placed 2nd overall out of 200+ teams.

My portfolio site (allenliu.dev). Built with Next.js, TypeScript, and Tailwind CSS, featuring dynamic photo galleries, interactive hiking maps, and Spotify integration. Actively maintained.

Course project (VIS208) published via GitHub Pages with multiple themed subfolders. A small static site showcasing intentional design and data visualization.

A COVID-era tracker that notified people when essential items came back in stock on Amazon. Followed my earlier AmznMonitor work, expanding notifications and heuristics.

An early monitoring/automation system that polled Amazon listings and sent notifications while handling anti-bot constraints. Precursor to BareShelves.
