User:Larma/Application 2019

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 and OpenKeychain.

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. 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.  In 2015, I participated in Google Summer of Code under the XSF to develop DNSSEC functionality for minidns. 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 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 and Occupant Identifiers.

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.
