Engineering projects with technical deep-dives by Yago Mendoza.

- Making clinical-trial search feel like booking a flight: A clinical-trial matching tool: describe your case or upload a report, and TrialGPT finds relevant trials near you, checks the inclusion and exclusion criteria against your situation, and drafts a message to the trial coordinator. - I am not a web developer: 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). - 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. - 72 hours to find out if I could: A bespoke CRM for a health-tech startup, built solo in a 72-hour marathon. Half experiment in vibecoding, half real product. 23 tables, 8 state machines, and a stale-detection system that knows when you're neglecting a psychologist. - Can you forecast a seizure with a spreadsheet and an LSTM?: A simulation-first rehearsal for forecasting a visual epileptic aura from the small visual events that may precede it, and a stricter measurement of what a model would actually be allowed to claim.
