Hello, I am Dimitris! Currently, I am working as a principal software engineer at the Medidata Knowledge Graph. I am also a Semantic Web researcher @AKSW/KILT group. Many people know me from DBpedia, where I was an active contributor and served as the head of technical developments for three years.
