A new product currently being built in private. More when it is ready.

Metis

Open source

An AI assistant for parents navigating high-conflict custody communication. It turns difficult messages into risk-aware, calm replies without giving up the boundary.

  • Started with a problem a friend was facing in a high-conflict custody dispute
  • Ran more than ten discovery interviews, then scoped and shipped a working MVP
  • Found early distribution in focused online communities, bringing in more than a dozen users
  • Reached 300+ visits in the first week

Built pro bono and released as open source , so it can be used and adapted without a paywall.

Live

Inspired by Swiss grids, printed matter, and unusually thoughtful software.

Trainstreak

Live

A training consistency tracker built around one simple question: am I showing up often enough to reach my yearly goal? It counts distinct active days, shows progress and pace across the year, and works with Strava and Apple Health exports.

  • Scratching my own itch: most fitness apps track distance, calories, or performance. I wanted to track what I actually cared about — active days
  • Track active days against an adjustable yearly goal. Explore pace, calendar patterns, sport breakdowns, and shareable summaries
  • Import Strava activities.csv or Apple Health export.xml directly in the browser
  • No account required and no personal training data is uploaded

Originally built around the Strava API. After Strava changed its developer programme in June 2026, I rebuilt the public version around official data exports. The result is simpler and more private: no OAuth gate, no API quota, and all processing stays on the user's device.
