About
employedAI Engineer @ Lemonade
Each of these started as "I wish this existed."
Solo-built, start to finish. The ones on this page are the recent ones.
Over fifteen years in software, currently AI Engineer at Lemonade. Everything here is checkable. Each project has a URL that runs and the date it shipped; where a post explains one, the card links it. The posts answer one question each and show the method and the numbers behind the answer, dated so you can tell when they were taken.3 of them run at their own URLs, 3 are public repositories you can read end to end.
The earliest of them shipped in 2025-01 and still runs; so does everything else on this page. The ship dates and the live links are there so you can check that yourself rather than take it from me.
Nothing asks to be taken on trust. Click any of them.
