Hello! My name is Sebastian Perez Saaibi, and I'm currently a Director of Data Science at Phreesia, the leader of patient intake in the US. I have 10+yrs of experience as Data Scientist, in both IC, startup founder and technical management roles across different industries such as mining, finance, retail and healthcare. I enjoy building teams of Data Scientists, Machine Learning Engineers and Data Engineers to come up with products that solve complex organizational challenges. I also enjoy mentoring technical managers and data scientists. I'm based in NYC and really look forward to share what I've learned in this journey while learning from others in the Plato network.

Sebastian is not available in the next 4 weeks.
