mantis‑analyzer — a small AI coach for the archery range.

It watches a shot — grouping, form, release — and writes back notes the way a patient coach would. Python and FastAPI on the backend, SvelteKit on the front, Claude for the read. It's the one project I'm spending time on right now, which is convenient: it sits squarely at the crossing of the two things I do.

I write code. Then I go shoot. Then the shots become data, the data becomes code, and the code quietly makes the shots better.

A single arrow's shot path, plotted from sensor data — release marked, follow-through traced.

A list of training sessions with dates and shot counts.
