Alexandre Catarino




I got my degree in Meteorology from the Physics Department of the Faculty of Science of the University of Lisbon in 2006 and spent the following years working on Climate and Meteorology models. After 13 years of Meteorology, I decided to use my knowledge of physics, math, and programming in the stock markets. In 2015, I found QuantConnect, started to contribute to Lean and became part of the team in 2016. At the moment, I continue to contribute to Lean, focusing on Python integration and implementing features at QCAlgorithm level to make quants' life easier. On top of that, I belong to QC Support Team.
