Things I've built with AI.

Small tools I build for my own life & the people around me. Each one links to the Jaslist post on how it came together & to the app itself.

Home & cooking

Digital Recipe Box

October 2026

A recipe box for the dishes I've made & trust, styled after Cooking Mama.

I've wanted a physical recipe book like the one my mother-in-law uses. Before printing anything, I made a digital version as a test run: the recipes I've cooked more than once & actually trust.

Each card has only the ingredients, the steps & my notes on what I change. Claude suggested plenty of extra features. I cut them to keep the first version simple.

Music & DJing

Afterglow

October 2026

Organizing my DJ library by how I actually DJ, built in 36 hours at a Lisbon hackathon.

Valerie & I built Afterglow at the Music Hackspace hackathon in Lisbon, answering a prompt about new ways to explore & organize music libraries. Instead of fixed playlists, it tags each track by context: when & where I'd play it, its role in a set & the crowd it's for. A lot of tracks fit more than one moment.

We tried 0–10 confidence scores & found they didn't add much. Tracks on the edge just get a simple "fluid, not core" flag.

Travel & friends

Constelaciones

September 2026

A summer travel tracker for 17 friends.

Every summer my friends scatter across different cities on different dates, & we keep just missing each other. Constelaciones shows where everyone is headed so we can actually meet up.

It grew past spotting overlaps. Now it also has shared itineraries, city recommendations & a board for trading tickets. A self-serve v2 is next.

Events & logistics

Wedding Website & Ops

September 2026

Three venues, 154 guests & a lot of vendor coordination.

We built our own wedding website instead of paying for a builder like Zola. The site was mostly read-only, & building it meant we controlled the structure & could update it instantly. Guests confirmed their RSVP by text, & each one saw only the Friday itinerary for their group.

Claude did a lot of the heavy lifting behind the scenes: reviewing vendor contracts, drafting seating charts, planning shuttles & turning a reference track into sheet music. Our coordinator worked from a view on the same database, so everyone had one current source of truth.
