About

I'm the Co-founder of GTLL, a company that builds private, HIPAA-compliant AI on infrastructure our customers own. We run AI automation for practices and professionals who can't put their data in someone else's cloud. At GTLL, every model is deployed on customer-owned servers — your data never leaves, and we never train on it.

Before GTLL, I taught myself Linux, learned to ship full-stack applications, and built tools like SmartSell and Scripta from scratch. I'm a sophomore studying MIS at the College of Charleston, bilingual in English and Spanish, and deeply focused on making AI practical, private, and provably secure for the people who need it most.
