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: vibes!
