Work.

Things I built and can talk about for an hour. Source is public on GitHub — read it, that's the point.

Apps

2025 — 2026
01

White Noise

A focus and sleep app built on a multi-channel procedural ambient mixer. Nothing is a looped sample: the sound is generated.

  • Custom AVAudioSourceNode blocks generate audio in real time, with binaural-beat layers cross-faded by a Pomodoro timer.
  • MVVM architecture with singleton audio and display managers.
  • SwiftUI interface with glassmorphic materials and procedural animation; an OLED-safe low-luminance mode for overnight use.

Harmonica Tuner

Real-time pitch detection for 10-hole diatonic harmonicas — it tells you which hole, whether to blow or draw, and how many cents off you are.

React Native · Expo

03

Ghosted

A conversation-exit assistant: paste the message you just received, get a polite way out drafted by an LLM.

  • Groq LLM inference behind two modes — generate an excuse, or soften a reply you already wrote.
  • UIKit with Storyboards and programmatic UI; usage streaks persisted locally.

SubSafe

An offline subscription tracker, published on Google Play.

  • Local-first by design: no account, no cloud, no data leaving the device.
  • Built with React Native and Expo as an end-to-end publishing exercise.
