I am Thorben, co-founder of Quarter Spiral, Engine Yard, San Francisco alumni and former founder of the German Rails shop kopfmaschine. As a developer I create large scale web applications. This holds true since my degree in computer science which was on "Scaling large Rails applications" and continued throughout my work at kopfmaschine and Engine Yard where I've built, maintained and migrated service-oriented architecture projects of all sorts. As a public speaker I share the insights on that with people from Baltimore to Singapore and from Gothenburg over Berlin to Dnipropetrovsk.
