I build products that run on their own: apps that act at the right moment instead of waiting to be opened.

01 // about

Software that does the next step for you.

By day I work on iOS build and release engineering. By night I ship with AI coding agents, fast, and measure whether it worked.

Most of what I make starts from the same question: what if the app moved first? A planner that asks "did it happen?" from the lock screen. An explainer that animates itself from one prompt. A sales agent that answers from the real price list.

Pacer

Runs your day so you don't have to. A lock-screen notification asks "did it happen?", one tap answers, and a replanner moves what didn't, with travel time and your calendar in mind. Gym blocks close themselves from Apple Health.

03 // how I work

Small, tested, honest.

  1. 01

    Small write paths

    One place changes state, so the UI and the assistant can't disagree.

  2. 02

    Pure logic, with tests

    The hard part lives in functions that are easy to test.

  3. 03

    Local-first

    Your data stays on your device unless it has a reason to leave.

  4. 04

    One honest doc

    Every project has its thesis, gates and gaps written down.
