Jakob Mahran Weissinger

I joined the team in November 2018. Being Ska's Social Media Manager, my main task is to take care of her online presence in the social web. This means, I coordinate online activities with other offices in the parliament, design visuals, answer to questions posted online or moderate discussions.

Throughout my studies (political science and economy) in Potsdam, Paris and Berlin, I worked for the Green Party in Brandenburg and in the office of Annalena Baerbock in the German Bundestag. Parallely, I was active within the party and in the board of a German-French association.
