My full name is Gregor David Trefs and I work in the field of software development. I have a masters degree in business informatics specializing in semantic web and data science. In my thesis, I tried to find a good way to rank SPARQL query results.

Since then, I had various jobs in IT. For example, I helped migrating software from one data center to another. I build a cloud management software in a small company as Research and Development Engineer. In 2015, I started and stopped graduating. Within this time I enabled a company to access its semantic data in an analytical way and created a platform for semantically integrating processes: github. From 2017 to 2018, I was a full time freelancer and then joined a company as Team Leader.

With 4 others, I organize the local Java User Group and founded the local software crafters community.
