AP CS Teacher. Cybersecurity Researcher. Open Source Developer.

I teach AP Computer Science and Cybersecurity at a college preparatory school in Florida. My AP CSP pass rate runs above the national average. Students land internships and reach out years later from their first tech roles. Outside the classroom I study what I teach. I hold rank #73 in the USA on TryHackMe, placing me in the top 1% of active security researchers on the platform.

I build software for the same reason I teach it. astroctrl is an open source telescope control system I released under MIT license. It runs on a Raspberry Pi as a dedicated astrophotography controller using raw INDI XML over TCP, no external library dependencies. My KU5E Academy platform delivers curriculum and assessments outside the traditional school system. My freelance work covers Python automation, Flask and Django applications, and security audits with full remediation documentation.

In January 2026 I weighed 350 pounds, carried a Type 2 Diabetes diagnosis, and managed hypertension with a full medication stack. By May I had lost 61 pounds and counting. My HbA1c dropped to 5.7%, the non-diabetic threshold, confirmed by lab draw. My doctor reduced my blood pressure medication by half. I built the system that produced these results, documented every component, and published it as the FACTOTUM Protocol. The protocol is a complete operating system for managing metabolic disease through food timing, protein targets, and structured meal prep.

I hold an MBA in Technology Management, work in both English and Spanish, compete in bowling leagues, and run a small manufacturing operation producing custom 3D-printed and laser-engraved products through MakerMindStudio.
