I’m a Software Engineer and Computer Scientist based in Switzerland.

On the technical side, I am excited about information security and computer systems, technical standards, cryptography, but also app development, system administration and devops.

All opinions on this website are my own.

Projects

A few noteworthy things I have worked on:

  • I’m a maintainer for FMD, a libre “Find My Device”-style Android app with ~15K users.

  • As an IETF working group member, I contributed to RFC 9788 “Header Protection for Cryptographically Protected Email”. My feedback led to a redesign of the scheme and more explicit algorithms (draft-20 to draft-21).

  • In my master’s thesis, I analysed the Proton Key Transparency protocol. The thesis, presentation slides, and Tamarin models can be found on GitHub.
