My name is Sebastian Cohnen (alias tisba, which is, in case you want to know, just a anagram version of Basti). I’m a freelance (web) developer based in Cologne, Germany and available for hire! My strong points are Ruby/Rails, high performance node.js backends, NoSQL databases (CouchDB in particular) and the design of scalable architectures for web applications.

I’m 28, live in cologne and I have a master’s degree in Computer Science (my thesis was about design patterns for scalable, service-orientated web-architectures). Furthermore I’m addicted to Club Mate and in love with all my Apple gadgets. Being thrilled by all kinds of web technology I’m always seeking for interesting new stuff. My desk is located here in Cologne and hosted by the mighty Galaxy Cats. Feel free to drop by – ClubMate is on me!

Besides German and English I also speak Ruby, JavaScript/ECMAScript and Java most of the time. I’m also trying to learn some new (functional) programming languages at the moment, in particular Erlang/OTP.

Feel free to ping me via @tisba or mail basti[-AT-]tisba.de.

Hire me! I’m available to work on your projects. Read more.
