I work as a Full Stack Web Developer at the lovely small web agency Railslove in Cologne, where I work together with our team and clients to ship awesome products on the web. I especially enjoy helping early stage startups to scale their business.
Besides client work I also have a couple of additional projects that I like to work on. This includes being an active facilitator of the local Ruby community (Cologne.rb, Railscamp) and contributing to numerous small open source projects.
My academic background is in Human-Computer Interaction (HCI) and I'm generally very interested in everything that happens between users, web applications and other users. Besides Frontend Development, this also involves UX & Interaction Design, Web Analytics, User Research, and Product Management.
These are the main clients have been working on as part of my work for Railslove
