Ernesto Vizcaíno Alvarado
Software Engineer & Founder
At 16 I started my first startup. It was Traver, a social network where every city had its own feed of posts, restaurants, services, and shops. I built it myself, then went business by business in San Luis Potosí getting them to join. I lost the domain, but it's still alive on Vercel. I've done the same thing a few times since: build something, then go sell it. I joined Oliver as a founding engineer and ended up as a co-founder. Then I was part of the founding team at Xignus, and now I run a few products of my own.

Rubin/LSST Light Curve Classification
1st place, Xólotl Hackathon · CUDI / LAMOD UNAM
Built a pipeline that classifies Rubin/LSST-style light curves, flags anomalies, and reports how confident it is. Trained on data from 5.1M+ objects and tested on 6,000 simulated curves from 600 observing cadences it never saw. The prize funded my trip to CARLA 2026 in Córdoba, Argentina.

I'm looking for an early-stage team where I can own a product end to end, ideally in applied AI. If you're building one, tell me about it.
