Welcome, here is my inconsistently-curated collection of software, writings, notes, and whatever, that I've created over the years.

Zazen
A no-frills Android meditation timer. Pick a length, settle in, sit with a bell at each end and a soft bed of noise in between. Every sound is synthesized on the phone. No accounts, no stats, no streaks.
Mood Ring
A private Android check-in app for noticing how you've been feeling. Quick mood nudges, an end-of-day check-in, and occasional standard questionnaires. No accounts, no servers, no analytics.
The Well Rounded Climber
An Android climbing log built on the idea that grades don't transfer between gyms. Track difficulty distribution and style variety instead — on-device, no account, no ads.
pexro
A personal mobile app that runs and tracks any exercise routine described by an uploaded JSON program. Have your LLM write the program for you.

react-zondicons
A dependency-free, small, fast, good-looking React SVG icon set.

agents: your first agent
Describe one agent and let the install draft it, run it on a repository from the terminal and the browser, read the run back in history, then edit it in the browser. The first of three tutorials.
agents: a pipeline
Put the changelog writer in a graph as one step, with a git read before it and a file written after it, read the cost of the whole run, then add a gate that sends bad work back. The second of three tutorials.
