The Mobility House was operating the selling and installing of the charging stations for BMW electric vehicles. The app used for this purpose uses a multi-step workflow system involving several parties (the car dealer, electrician, BMW headquarter, ...) that needs to be modeled in software. The project was based on Ruby on Rails 3.2, MySQL, Apache, and Phusion Passenger. The development was run using an agile process (1 week sprints, Kanban style board, weekly retrospectives, code reviews) with a distributed multi-national team. As the codebase was already a few years old emphasis was placed on improving the code quality through code reviews, refactorings, and tools like Code Climate.
I was part of the development team as an external contractor and also automated the setup of the server infrastructure using Chef solo.
Bonjour Bonjour is a French startup that provides a localized social network on portable devices. I'm working on the server side API part which is written in Ruby on Rails. The work includes rewriting big parts of the application to allow for scalability, while at the same time not interrupting the operation of the service.
After writing the initial implementation in 2007, I'm now again working on this project. I develop (small) new features and I keep the site running as it should. This includes server maintenance and upgrades of the underlying software (Ruby, Ruby on Rails, ...) as well as bug fixes.

A small web app for a single event. The homepage design was provided as a PSD file. I implemented it using Ruby on Rails, TypeKit fonts, and Twitter Bootstrap. The app also includes a ticket sales system with payments through Paypal and the app generates the personalized tickets as PDFs.

Finished with a German Diplom (equivalent to a Master). The emphasis was on data mining and machine learning, which of course includes data visualization. Due to the large amount of data produced in this field of science I also know my way around big data.
