Now.

What I'm working on this month. Updated when something material changes — not on a schedule.

Building

An AI wellness companion for iOS — in active development. Bedrock-backed, on-device privacy where it counts.
A v2 of MedCore for a Long Beach hospital group.
This site (louiscastaneda.com) — Astro + AWS, in public.

Training

Grinding from a 220 to a 225 bench. Closer than I want to admit, farther than I expected.
Three lifts a week, one conditioning day. Plain spreadsheet log. InBody scan on the first of the month.

Reading & thinking

Working in Public by Nadia Eghbal — re-read.
Kalshi every morning with the coffee. Reading prediction markets like a news feed.
Teaching middle schoolers to use AI. They are sharper at it than most adults I know.

Not doing

Twitter as a content channel. The signal-to-noise is too low for the time it costs.
New client work until Q3. The calendar is intentionally light.
