I'm building Armocromia, a Chrome extension that tells you whether the item you're looking at online actually suits your coloring. Three questions work out your color profile; the extension then scores the product page against your palette and explains the score.
It's the fashion interest and the product instinct in the same place, and it's teaching me to do the thing I usually manage. I'm writing it myself, in React and TypeScript, one broken build at a time.
The design decision I care most about: three questions cannot determine anyone's true season, so the product says a likely direction and shows a match band rather than a fake 100% score. Overclaiming precision is the fastest way to lose someone's trust, in a shopping tool or in a program status report.
Outside that: fashion, travel, coffee worth sitting down for, and enough time outdoors to reset between launches.
