Before becoming a consultant, Steven studied Econometrics at the University of Amsterdam and worked in the financial industry. He decided to become a data scientist after investigating how sentiment derived from social media text data influences financial markets. His work got published in the Journal of Behavioral Finance. Although the algorithm didn't make him rich, he gained valuable experience in modelling and programming. Something that he now teaches to clients at GoDataDriven.

Steven is a data and travel enthousiast. In his spare time he combines both passions by building a recommendation engine for travel inspiration. Need a suggestion for your next trip? Check out his hobby project Stairway to Travel.

Please feel free to contact Steven if you want to know how Data Science or Big Data could be relevant to your organisation.

Clients include: KLM, Dynniq, and Randstad
