01Hello, Earth

The short version

I have 4+ years of shipping production software. By day I'm a Front-End Developer II at Applied Medical, where I went from junior to developing a flexible in-house Jira alternative tailored to the company's workflows.

Things I've built

01

Split It

Open app

Splitting the bill, down to who had which item.

Take a photo of a receipt and a vision model on my own Mac Mini reads every line. Photos are never stored. Around that sits a full expense app: groups, four ways to split, simplified debts and settling up.

  • Next.js 16
  • Hono
  • tRPC
  • Drizzle
  • PostgreSQL
  • Ollama

HK Mahjong

Play a game

Four-player Hong Kong mahjong in the browser.

A Rust game server with a Next.js front end. I directed the build against a written rule spec, and 280 black-box conformance cases check the server against it.

  • Rust
  • axum
  • WebSockets
  • Next.js 16
  • Tailwind CSS
03

Voice Assistant

A voice assistant that never leaves the house.

An ESP32-S3 listens, Whisper transcribes, a local Ollama model thinks, Home Assistant acts and Piper talks back, all self-hosted on a Mac Mini and a Raspberry Pi with zero cloud.
