I'm a cybersecurity architect, instructor, and thought leader with over 20 years of combined experience helping organizations strengthen their security posture across government, financial, and enterprise sectors. Known for bridging the gap between technical implementation and executive decision-making, I bring clarity and strategy to an often-complex security landscape.

My mission is to empower organizations and individuals to make risk-informed, data-driven security decisions.

Cryptography, privacy, quantum security, infosec, retro vibes.

I am a mathematician and computer security scientist, with a strong interest in cryptography and anonymity, specialized in quantum security and complex cryptographic protocols. I am also a privacy hacktivist and public speaker, blahblahblah, read my Linkedin bio for this s**t, this is my Mastodon corner.

I co-develop Shufflecake, an open source privacy disk encryption tool to help journalists, activists, and whistleblowers evade unjust prosecution.

I am an advocate of digital self-sovereignty. You will see me often ranting about Big Tech, enshittification, and surveillance capitalism.

Fascinated with anime, Japan, RPGs, retro computing, and all things 80-90's. Notice I wrote "fascinated", not "knowledgeable".

Here you won't find peace nor forgiveness, but just: #cryptography #privacy #quantum #security #infosec #retro vibes!

Long time #Unix (v7, BSD, Solaris), #GNU #Linux, and #Emacs user and developer. Programming mostly in #JuliaLang but also #Octave. Into #cycling 🚲 and dismayed at #Brexit 🇪🇺.
