BIO
I'm a Software Engineer and I love to apply AI in the industry. After obtaining a PhD in Machine Learning, I joined Google to work on Computer Vision for Android and NLP for the Google Assistant, where I owned the Weather vertical. I left to start and lead a ML Team at the 90-year old Rohde&Schwarz. There we patented and launched metrics for Data Analytics based on Deep Learning. As a founder at Trackingplan, I'm managing the technical department and people coordination.
