About Me
I am contributing to and developing open-source software since 2011. Most of my work is related to the Android operating system. Projects I significantly contributed to (and are not mentioned in the next section) include microG and OpenKeychain.
I graduated with a master in computer science and am a self-employed software engineer. I currently live in Berlin, Germany.
Me and XMPP
My first development activity around XMPP in 2012 was an open-source client for Android based on Smack. [1] It was a total mess and I discontinued work on it just a few months after publication. I also experimented with a system-wide XMPP service for Android in 2014, but it never became useful for anything. [2]
In 2015, I participated in Google Summer of Code under the XSF to develop DNSSEC functionality for minidns. [3] While originally developed for the use in Smack, it is now also used in Conversations as well as many other projects. Starting 2018, I (co-)mentored Google Summer of Code students.
Since 2016, I am one of the main developers of Dino. I regularly participate in development sprints and help advertise XMPP on conferences. I am happily contributing my opinion on the mailing list and in xsf@ MUC. I became a member of XSF in 2019. Since 2021, I serve on the XMPP Council.
My personal interest in XMPP is user-friendly and secure personal and team communication (chats and calls). I am happy to contribute further to XEPs as well as Dino and other XMPP-related open source projects, to make this reality.
