Hi there 👋 I'm Lukas, a machine learning engineer and full-stack developer from Berlin 🇩🇪 I like to explore disruptive ideas and build simple tools that solve real problems from initial architecture to a production-ready solution.
During the last few years, I have focused on building scalable data solutions involving Machine Learning, Knowledge Graph, and NLP technologies. Previously, I created mobile & web applications as well. On the side, I'm also building open-source tools. You can find some of my professional and personal projects below.
