Open-source software developer focused on instant messaging and email

I’ve been a freelance software developer for over 15 years. My main interests lie in open standards and communication protocols, including instant messaging, email, and the fediverse. I’m the project lead for Conversations and Ltt.rs. Occasionally, I also dabble in security research.

Most of my open source projects are hosted on Codeberg.

I’m an active member of the XMPP Standards Foundation (XSF), serving as the chair of the council and as a member of the editor team.

This website primarily serves as a landing page and a platform for publishing long-form content. For shorter, more frequent updates about my work, you can check out my Mastodon.
