My Projects

This page is work in progress. For now it's only an unordered list of the things I can remember. I'll prettify it later :)

- started in 2003 with HTML, PHP, MySQL, was fascinated by Google, tried to build an own search engine (which obviously failed due to performance issues)
- started an online community in 2005 called Xairro.com (first PHP, later Django)
- helped building Germany's former most successful freehoster Redio.de
- found a major security hole on StudiVZ.net (was the largest German social network back then)
- found a major security hole on ruf.de (a German travelling agency)
- won some robotics-competitions
- built a system for my former school to manage the student's working groups (and got them to switch to Linux and helped re-building the school's network)
- a tool to extract your WhatsApp chat history from the database taken from an iPhone backup

== smaller weekend-projects that I abandoned or didn't become successful ==
- a PHP-ORM system for a client because I didn't like the existing ones
- a Python-based "TweetRank" system that used a PageRank-like algorithm to rate the influence of Twitter-users, but it failed due to the Twitter API restrictions a lack of computing power
- a Python-based news-aggregator that used some AI to build a single article out of several ones covering the same subject, but it failed because some news-agencies obviously didn't like it
