// 01 — About

The Developer

Twenty years of building software that gets used. Not prototypes — production systems running daily in government agencies, utilities, and enterprises across Puerto Rico.

Currently a Senior Developer at Truenorth Corporation, maintaining and designing critical applications for public-sector clients including the Puerto Rico Aqueduct and Sewer Authority (AAA), the Department of Education, and CFSE. Systems I build are expected to last — and they do.

Outside the terminal: a dedicated gamer drawn to deep, punishing systems — Path of Exile 2, Elden Ring. The same patience that clears endgame content goes into production code.
