Software Developer in Konstanz, Baden-Württemberg, Germany

For a large publishing house, I planned and developed a rights management solution to reduce costs for acquiring reproduction rights. It is a complex single-page application built on AngularJS.

BaseX is an XML database and XQuery 3.0 processor implemented in Java. I am a core developer and do testing and bug fixing for the BaseX core product. I develop a replicated and distributed version of BaseX for improved performance and fault-tolerance. I also added modular functionality, e.g., a random module or a templating system based on Mustache.

I architected and implemented a solution called NAPERS for the application and reviewing process of young researchers for the Lindau Nobel Laureate Meetings. It uses an external data storage, which we connect to using OData. The platform itself is programmed in XQuery using RestXQ; the client-side is done using AngularJS (JavaScript). I did the implementation, testing (JUnit, Selenium), and architecture of the system.

This project is an internal communication platform (including a wiki, shoutboxes, forum, polls, task management, calendar, ...) based on OpenAtrium (PHP5, MySQL, LAMP), and is implemented for a German Non-Profit-Organization called Studieren Ohne Grenzen (Studying Without Borders). I set up and enhanced the platform and migrated content from an older legacy solution. I also enhanced the login functionality to work with proprietary pre-existing user profiles.
