ROSARIO, AR · ● AVAILABLE FOR WORK

Ignacio Joaquin

Full stack developer in Rosario, Argentina. I build web products end to end — frontend, backend, data — and I also teach at IPS, which mostly means being corrected by thirty people at once. This is where I keep notes on what I'm building and the things I got wrong before I got them right.

Hello, and why I'm writing this

Starting a blog mostly so I stop losing the same notes to Slack threads and half-finished gists.

A webhook spoofing bug that made it to production

The signature check was there. It just wasn't checking the thing that mattered.

//Things I built

2026ML · Random Forest · Data pipeline

SoyGuardian

Built at HackitBA 2026 (ITBA Computer Society) as Technical Lead. A B2B platform for banks and insurers to assess agricultural credit risk: a Random Forest model estimating crop yield, and a data pipeline pulling satellite and weather data from NASA and CONAE for continuous field monitoring at a fraction of an in-person appraisal's cost. Didn't advance to the final round, but the modeling and pipeline held up.
