Ruby on Rails is my primary technology focus. I conducted several projects as a developer and lead developer. Rails and its test driven and rapid prototyping approach go very well with my focus on agile development methods.

Since my first contact with Ruby on Rails in 2005 I have been developing Rails applications. I conducted the first RoR project for a client in 2006 (e-tecture GmbH). From that time on I was also engaged privately in RoR, especially viewing the framework in the light of my focus on software engineering methods. In between projects I evaluated RoR as a framework for online games. Since a JRuby project for a client in 2008 (Vanteno GmbH), where I was employed as a Rails expert, RoR became my primary technology focus. I built several homepages with CMS elements and a Web 2.0 musician tool suite in RoR between 2008 and 2009. In my latest RoR project at LiveSein, I lead the development of a social community application with live video interaction.

Ruby on Rails continues to be my technology focus and I am staying on the edge of RoR development and keeping track of the ecosystem with its methods/opinions, plugins/gems or future developments.
