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.
