Projects

Engineering projects with technical deep-dives by Yago Mendoza.

- Infraphysics — building a website that thinks: How a systems engineer built a personal site with a custom markdown compiler, a second brain, and an AI development partner — and what went wrong along the way. - FinBoard — a personal finance dashboard for the crash: A vanilla JS investment dashboard built in one session with Claude 4.6. No framework, no build step, no npm install. Just a folder you double-click. - Building a custom CRM for a startup: A bespoke CRM for a health-tech startup, built from scratch in 5 days. 23 tables, 8 state machines, and a stale detection system that knows when you're neglecting a psychologist.
