Hi, my name is Mikio L. Braun and I’m Delivery Lead at Zalando, a pretty big fashion retailer in Europe (which probably explains why you haven’t heard of us yet). Delivery Lead is kind of a technical lead role. I’m currently responsible for two teams, one doing the recommendations, and one team building the next search at Zalando. Before joining Zalando I was a PostDoc in Machine Learning at TU Berlin (heck, I’m even a co-author on a deep learning paper!), and had a “startup on the side” called streamdrill on real-time data analysis.

I’ve always been interested in the whole range of tasks related to solving problems, from the math and theory down to actually building the whole thing and making it run. Although I have worked on pretty theoretical stuff, as well as very practical stuff, I really like to work on things which combine both, ideally concrete problems which contain some real technical challenges.

With my new job at Zalando I am now formally going into management, which I found highly interesting but also challenging.
