About me

I'm a data engineer based in Monterrey, México. I like building pipelines and systems that keep data trustworthy enough to actually make decisions on. Day to day I work mostly with Python, SQL, and AWS.

I studied Data Science and Applied Mathematics at Tecnológico de Monterrey, which is a long way of saying I spent four years on statistics, ML, optimization, and enough math to be dangerous with. The mix shapes how I approach messy data: I'd rather model the problem properly than patch around it.

Right now I'm at Enviaflores.com, where I build and maintain the data systems the rest of the company runs on. It's a fast shop, which has taught me to prioritize reliability over cleverness. A pipeline that doesn't fail at 2 a.m. beats one that's elegant but fragile.

Off the clock I read a lot (recent reviews are on the Books page) and I'm slowly getting deeper into coffee. Both are good excuses to slow down. If you want to talk about either, or about a data problem you're stuck on, the Contact page is right there.
