Selected work

Four things I’ve
made from nothing.

  1. 01

    Haste

    AI calorie tracker 2026

    A food journal that makes logging fast enough to keep doing. Snap, say or type a meal and AI estimates the calories and macros.

    • One Flutter codebase for iPhone and Android
    • On-device speech recognition, so recordings never leave the phone
    • A cited New Zealand food catalogue and barcode lookup
    Role
    Design, engineering, release
    Built with
    Flutter · Dart · Supabase · Postgres · On-device Whisper
  2. 02

    Burble

    AI note-taking 2026

    The notebook that organizes itself. Notes, tasks and handwriting, filed by AI into open files in your own cloud.

    • Local-first: every edit works offline and merges without conflicts
    • A portable TypeScript core shared by iOS, Android and the web
    • Full-text search over an on-device SQLite index
    Role
    Product, design, engineering
    Built with
    TypeScript · React Native · Expo · Yjs · SQLite
  3. 03

    Cairn

    Universal pedal Concept

    A universal pedal that brings production sounds to the stage, for any instrument or voice. Not just a guitar pedal.

    • A hardware idea taken from a gap in the market to a full plan
    • Research into what exists and why it falls short
    • Engineering, hardware and business mapped out before any build
    Role
    Founder, product concept
    Built with
    Product research · System design · Audio · Hardware
  4. 04

    Kokonut

    Independent studio 2026

    The studio behind all three, and this website: hand-written WebGL, no framework, no trackers.

    • Every 3D scene on this domain is modelled in code
    • Static pages with a strict content security policy
    • Automated checks on every push
    Role
    Founder
    Built with
    JavaScript · Three.js · GLSL · Web Audio · CI

About

I take ideas
the whole way.

I’m a student at the University of Auckland and the founder of Kokonut, a one-person studio. I take products the whole way: the idea, the interface, the code, the backend and the release.

Most of my work is AI that earns its place. Haste turns a photo into a meal log you can check. Burble files a thought where you’d have put it yourself. Cairn is my plan for taking the sounds a musician makes in the studio onto the stage.
