☕️ Insufficient Coffee


The Author

I am a Cryptography Engineer at Mozilla. In the past I built-out the back-end infrastructure that Let’s Encrypt used when it launched and still serve on their Technical Advisory Board. A long time ago I co-founded SAIFE, Inc. and purpose-built a high-performance public key infrastructure.

I’m a co-author of the W3C Web Authentication specification, as part of my goal of replacing passwords everywhere I can.

I’m also an active private pilot and occasionally post about aviation topics under the heading aviation.
