Ernesto Vizcaíno Alvarado
Software Engineer & Founder
I write the code, ship it, and go find the users. I started programming at 13. At 18 I launched a point-of-sale app that reached 3,000 active users in three months. Since then I co-founded Oliver AI, built a credit model that got small businesses MXN $4M+ in financing in its first month, and won the Xólotl astronomy hackathon.

Things I built, and what happened when people used them.
- Applied AI · FintechCo-founder, led engineering · Customers incl. Abaco CapitalI co-founded Oliver AI and built its fintech platform. AI agents reviewed lending risk and processed financial documents, and AWS/BigQuery pipelines turned bank data into credit analysis.
Oliver AI — AI agents for lending
- (opens in a new tab)Applied AI · Data EngineeringMXN $4M+ in financing for small businesses in month oneA model that preapproves small businesses for credit from their bank, tax, and financial data. I built it and the AI workflows around it, then came back to connect CONTPAQi accounting data and automate reports with ETL pipelines.
Xignus AI — Credit preapproval

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.

Universidad Autónoma de San Luis Potosí
Built a classifier for periodic variable stars from 491,073 Gaia sources and 91 features (time-series, Fourier, color, and catalog). Class-weighted XGBoost reached 0.9495 macro F1 on a held-out split. Checked separately against mapped OGLE labels, it reached 0.9847 weighted F1.

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.
