2021 until today

komoot GmbH

komoot is a mobile app and website for navigation and route planning for outdoor activities. It was founded in 2010 and has, as of March 2025, over 7 million monthly active users (45 million total) and is the leading outdoor app in Germany and other European countries.

I joined komoot as a Senior Backend Engineer in October 2021 and started in the Monetization squad, which handled all payment related areas as well as owning most of the premium features. In late 2024, I switched to the "Developer Productivity" squad, which was founded out of internal need from the backend team.

In March 2025 the company was bought by the Italian technology company Bending Spoons which laid off a large percentage of employees, including myself, in early April.

keeeb GmbH

keeeb was initially developed as a platform to collect and share information (think Evernote/Google Keep/etc.) on the web. After a pivot we focused more on the enterprise sector as a tool for collective information gathering and knowledge storage. I worked here part time during my time as a student and later as a full-time developer.

2011 - 2015

Universität zu Lübeck

M. Sc. Computer Science

After my bachelors degree I wanted to learn more about the theoretical part of computer science so I started a masters degree. During this time I also started working at keeeb part-time so the study took longer than anticipated. I graduated with the final grade “good (1.9)”.

2008 - 2011

Technische Hochschule Lübeck

B. Sc. Computer Science, Software Engineering

After my apprenticeship I decided that I want to work in software development so I enrolled in Lübeck. During my time here I was also part of a student organization (Fachschaft Technik & Wirtschaft). I graduated with the final grade “good (1.7)”.

2005 - 2008

Kromberg & Schubert

After school I started an apprenticeship as IT specialist (Fachinformatiker für Systemintegration). I did network and phone system management, unjamming printers, user support and general IT related tasks. After I finished the apprenticeship early I also worked here for a few months until my bachelors study started.
