Marcel Jahn


Marcel joined sum.cumo in December 2018 as a frontend developer. Together with his teammates, he takes care of various frontend needs, primarily for clients in the insurance industry. Before joining sum.cumo, Marcel worked as a frontend developer at Krankikom GmbH in Duisburg. There, he was mainly active in developing websites and booking systems for movie theater chains. At sum.cumo, Marcel likes the fact “that everybody pulls together. Teamwork is highly valued, including between our different locations.” In his work, Marcel puts great importance on unifying setups and structures wherever possible. This makes it faster to set up new projects, and also makes it much easier for colleagues to find their way into a new project. In his free time, Marcel likes riding his mountain bike through the nearby forests and whiling the hours in his small woodworking shop.
