I’m a software developer from Berlin, working for Talon.One GmbH.

I’ve been involved with programming and software since my highschool years a the Steinbart Gymnasium in Duisburg. I studied Computer Science at Dortmund Technical University. In my diploma thesis I developed the concept for a web development framework for Serverside JavaScript, outlining a potential future that has since become widespread reality with the advent of node.js.

I took my first steps into software with PHP3 and Java around 1998. Since 2004 I did mostly serverside development in Ruby on Rails. I first loved how Ruby extended my horizon and became fascinated with all sorts of programming languages and paradigms ever since. Over the last few years I’ve drifted more and more towards frontend and full-stack development in JavaScript.

I take a holistic approach to software development, combining my theoretical knowledge from studying CS with my practical experience in designing and implementing complex software systems.

I love my MacBook, I enjoy taking photos with my Nikon D90, I like music, movies, food and art. You can meet me at the berlin.js meetups or at the AngularJS Meetup Berlin that I’m organizing.
