About me
Why Nezzontli?
Nezzontli is inspired by Náhuatl. It is not a literal translation but an interpretive concept meaning “my path.”
The name frames this site as a technical logbook: a record of how I think, build, test, and learn.
This space documents projects, experiments, and notes that sit at the intersection of physics, software, and systems engineering. It is also a space for exploring the intersection of technology, privacy, and human rights—particularly how open-source tools and cryptographic systems can empower individuals and communities.
Philosophy
“Precision over noise. Systems before tools. Understanding before optimization.”
I believe in the power of privacy as a fundamental right, not a privilege. Technology should serve human dignity, autonomy, and freedom. Whether through secure communications, open-source software, or decentralized systems, I am committed to understanding and building tools that protect individual sovereignty in an increasingly surveilled world.

“The only way to deal with an unfree world is to become so absolutely free that very existence of such a world is a form of a profound insult.” — Ayn Rand
“Privacy is not about secrecy. Privacy is about freedom.” — Edward Snowden
“La privacidad es necesaria para una sociedad abierta en la era electrónica.” — Eric Hughes, A Cypherpunk’s Manifesto (1993)
