Hi, My name is Marvin Wißfeld, I also go by the nicknames larma and mar-v-in. This is my application to become a member of the XSF.

About Me

I am contributing to and developing open-source software since 2011. Most of my work is related to the Android operating system. Examples of projects I significantly contributed to (and are not mentioned in the next section) include microG [1] and OpenKeychain [2].

I graduated with a master in computer science and am a self-employed software engineer. My research and professional focus is in mobile privacy, IT security and fintech. I live in south-western Germany.

Me and XMPP

My first development activity around XMPP in 2012 was an open-source client for Android based on Smack. [3] 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. [4] In 2015, I participated in Google Summer of Code under the XSF to develop DNSSEC functionality for minidns. [5] While originally developed for the use in Smack, it is now also used in Conversations as well as many other projects.

Since 2016, I am one of the main developers of Dino [6] and co-mentored Google Summer of Code students for Dino in 2018 and 2019. I participated in sprints in Cambridge (2018), Karlsruhe and Lyon (2019) and plan to join the sprint in Stockholm. I (co-)proposed two new XEPs, Reactions [7] and Occupant Identifiers [8].

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.
