About

Industrial civil engineer (UDD) who learned to program at the SoyHenry bootcamp in 2022 and has not stopped since. Today I build Biovity, fasty and corvo on my own time, and lead open source programs at indies.la.

At Tigo Chile I work as a Marketing B2B Apprentice Analyst: SQL Server queries across business schemas, Power BI dashboards the sales team checks daily, and reporting automated with Power Automate.

I like fintech, data analysis, and building products people actually use.
