A friend sent me the Charlie Wilson 2023 Tiny Desk Concert clip and I kept thinking: everyone should get to be in that band. So I built https://tinydeskai.studio . You upload one to five photos. The f

I wanted a simple place for daily calculations - So I built one.

How I built a countdown & days-since tracker with React 19, Supabase and Vercel

I wanted a place to count down to things – a trip, a birthday, a deadline – and to count up from things, like the day I started a habit. Most countdown sites I tried were full of ads or wanted an acco

I built a USDC checkout with no payment processor, ~400 lines of Python stdlib

Most "accept crypto" options either want KYC or take a cut. For a small digital shop I wanted neither, so here's the design: 1. A unique amount per checkout. A 15 USDC product becomes 15.000437 USDC.

I built a dragon name generator in one HTML file - the trick is hiding meaning in the roots

Most name generators spit out syllable soup. When I built dragonnameforge.com (a free dragon name generator, single HTML file, no backend), I wanted every name to carry its own lore. So the whole tool

VideoFloppy: Five Years, Ten Users, One Dollar
