Race Timer
A standalone Wear OS race timer that runs the ISAF and US Sailing start sequences on the wrist. Cues are scheduled rather than polled, which is the difference between a horn on the gun and a horn near it.

I build sailing software — the boat is the
test rig
. A race timer that runs the start sequence on a watch,
BLE control for robotic race marks, and the club tools underneath
both.
Selected work
Three, explained properly
Three projects with a decision worth defending beat ten thumbnails. The rest are a line in the index.
Buoyant
Cross-platform BLE fleet control for GPS station-keeping robotic race marks — set, move and monitor a course from the committee boat instead of dragging anchors.
Burgee
Regatta and yacht-club management: entries, scoring, protests and the committee-boat side that every desk-bound incumbent leaves out.

About
Short version
I sail a Thistle on Lake Erie and write the software I wanted on the water. Most of it starts as a problem on a race course and ends as something small enough to trust with a start sequence.
