I’m Florian from Hamburg.

I like creating things. As a computer scientist by training, these are mostly digital in nature.

With passion, I spend my workdays as a Senior AI Engineer at Twenty Billion Neurons in Berlin. We use neural networks and other exciting technology to build a fitness product that can do things not possible a few years ago. 

I like working with people and collectively finding out how best to work together. This is possible in my role as a team lead and Scrum Master, where I can learn new things every day, which I am grateful for. 

In a previous career, I worked as a web developer, which has taught me a lot about thinking about the user, and not only the technology.
