Sebastian Carlsson / Freelance Interactive Developer


I'm a Swedish creative technologist and interactive developer living in Berlin since 2012, working as a freelancer since 2013 (registered in Germany).

I attended the renowned Swedish creative business school Hyper Island, and have been working professionally in the advertisement industry since 2006, with full-time positions at digital studios such as Delete London, North Kingdom and ACNE, in London, Stockholm and Berlin.

I've been working as a creative technologist and/or lead developer on award-winning projects of all shapes and sizes for a multitude of clients in Europe and the US such as Netflix, adidas, H&M, IKEA, BMW, Mercedes-Benz, Renault, General Electrics, the Swedish Armed Forces and Bang & Olufsen.

My philosophy is to put humans as opposed to technology in the centre of attention, and for that reason I apply a pragmatic, UX-focused "end-user-first" approach to every project I’m involved in. I have a deep understanding of programming for the web and a documented ability to ship maintainable, top quality code in highly pressured situations.
