26 projects: products and platforms I led, open-source tools I maintain, and freelance builds for clients. Each page covers what it does, the stack behind it and, where I wrote one, the story of building it.

2026 - Present
A privacy-first Expo app that combines cycle, movement, water, meals, and Quiet Time tools with optional health connections. Works fully offline as a guest; accounts, encrypted cloud backup, and multi-device sync are opt-in. Not a diagnostic or treatment system.
