Updated November 2026

  • Building

    A decentralized AI platform, in development: one AI model, split across computers people already own, with the work checked. No outside computer joins before a security review.

  • Researching

    How to verify AI computation on consumer hardware you don’t control. Honest machines never compute exactly alike, so every check needs a tolerance, and a careful cheat can try to hide inside it. One paper goes to peer review this month; two more are in preparation.

  • Talks

    Available for seminars and talks on checking AI work done on untrusted hardware.

Work

Building since school.

I started building apps in Dubai while still at school. Since 2023 I’ve been at Amazon in London, where I moved from data science and analytics into engineering.

A Shadow of Time

I built a world, then wrote its music.

Two parallel stories. A mysterious voice shares moments from its life when time stopped, as you cross forests and snowy mountains, solve puzzles and restore time to the world.

  • A hooded character walks a grassy path through a pink-leaved forest.

    01 — The forest path

  • A snowy plain with bare trees under a blue evening sky.

    02 — Snowfields at dusk

  • Grassy hills and rocks under a lilac sky.

    03 — Lilac hills
