I take digital products from vague idea to live and used.

Four builds, shipped

My own products, discovery through to production. Twenty years in, I still do the work myself.

1. Deucey

   Apple Watch + iPhonePadel scoring that gets out of the way of the game.

   Four players, one score, and nobody sure if it's 30-40 or 40-30. Every argument about the score is a rally not played.

   I own it end to end: the product spec, 25 user journeys, the design system and the Swift build across watch, phone and a shared rules engine. You score from the wrist without looking. The phone calls the score out to the court in a real umpire's voice, so all four players keep their heads in the point.

   

   

   

   • Eyes on the ball

     Score with the crown, a swipe or a double tap, without looking. A distinct haptic tells you whose point went in. A single tap never scores, so a sweaty wrist can't change the match.

   • The court hears the score

     Every point called through the phone or a Bluetooth speaker: deuce, golden point, set point, tiebreaks. 196 recorded clips, each checked by speech-to-text before it shipped.

   • Either hand, either wrist

     It detects which wrist the watch is on and which side the crown sits, then maps every gesture so the near side of the net is always your point. A manual flip covers the edge cases.

   • Never drops a point

     Each point is an event on an append-only log, so nothing gets overwritten. The watch keeps scoring if the phone drops out, and they reconcile the moment it's back. Undo and correct in one swipe.

   • Real padel rules

     Golden point, the new star point, advantage, tiebreaks and super tiebreaks, all set before the first serve. Props in landscape as a courtside scoreboard, readable from the baseline.

   • A little banter

     Ten lines tied to real moments in the match: a third game on the bounce, a bagel on the cards, a tiebreak. Never the same line twice in a day.

   Hear the umpire

   • "Tiebreak. Nobody breathe."
   • "Bagel incoming. Someone fetch the cream cheese."
   • "You're paying to get beaten, remember."
   • "Deuce again? Someone just win it."
   • "You could maybe start playing now?"
   • "OK, now the comeback starts."

   Coming nextVideo

   Every point is already a timestamped event, so syncing Deucey to court video is a join, not a rebuild. Every rally clipped and indexed by score, "show me every break point we lost" in one tap, then shot and positioning analysis on top. The score becomes the spine of the match data.

2. Domestique

   Weekend buildAn agentic cycling trip planner.

   Planning a multi-day ride means juggling routes, gradients, daylight and where to sleep across a dozen tabs.

   Ran the discovery, designed the agent loop, built it. It turns a rough ambition into a day-by-day tour: routes, bike-friendly stays, weather, cafe stops. LLM-as-judge eval suite behind it.

3. Eleo Jobs

   In daily useA white-labelled recruitment engine.

   Job boards return hundreds of near-misses and no sense of which roles are actually worth a reply.

   Built and shipped a recruitment engine, then white-labelled it as a product: it pulls roles, scores each against a profile with an LLM, and ranks a shortlist with the reasoning attached. I run my own job hunt through it.

4. VeloLog

   macOS + KarooA native training app, Mac to head unit.

   Structured indoor training means a subscription, a closed ecosystem and someone else's idea of a workout.

   Built a native macOS training app in SwiftUI: ERG-mode structured workouts driven over ANT+, live power, cadence and torque, then deep post-ride analysis: mean-maximal-power curves, time in zone and a FIT export. It also runs on the bike, a companion Hammerhead Karoo app in Kotlin with custom on-device data fields.
