Excited for the rise in distributed open systems again, reminds be of the 80/90's shift, start of Linux, irc, of which I was a part of by advocating for freeing the code and installing the 2nd server, after Oulu.

Cryptographic & Security Engineering

Previously: Founding & Lead iOS Engineer @signalapp

Tooting on all things #cryptography, #lithography, #energy, #security, #mobility, #climate, European #aerospace and federalism.

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.

I'm a cybersecurity professional, licensed amateur radio operator, and tech enthusiast. I also make music and burn my fingers with soldering irons.

I usually follow back if I see proof of life. :)

SW craftsperson & technology enthusiast, emphasis on security #SpielerischeSicherheit.

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!
