Initially as a freelance web designer & developer. I also financed my studies in Digital Media at the University of the Arts Bremen (2009 - 2013) independently in this way.In 2021/22, I sold the crash detection company Tocsen (presentation on German TV Show ProSieben, Das Ding des Jahres), which I co-founded in 2018, to the british company Aleck (sazbike article).As part of the sale, I was employed as managing director of Tocsen GmbH from 2022 to 2024 as part of the transition process and thus responsible for the EU branch of the Aleck Group and CTO of the group.During my time at Tocsen and Aleck played a key role in shaping the product and defining the technology stack, built and led multiple software teams, and was responsible for a wide range of business operations – as is typical for founders. We shipped hundred thousands of bluetooth crash sensors and audio devices with even more app installations and users.Independently of this, I have been founder, shareholder, and managing director of Brainspin  since 2017 – a web development agency that grew out of my former freelance business. From 2017 to 2024, we had a team of five and worked with clients such as Reishunger, QLF, Fairfood or Ergotopia.I put the agency business to a hold in 2025 and transformed Brainspin into my holding company.Currently, together with my brother Torben (founder and board member of Reishunger), I am building an E-Commerce and a manufacturer brand (Shield N Show) in the collectibles sector – with a focus in business automation and brand creation.
