BeatleTech is my (Coen Stevens) holding company where I offer my services, skills and expertise in web development, software architectures and Data Science.

Software Architect and Data Scientist

Currently I'm both Chief Architect and Data Scientist at Bottlenose, a trend intelligence platform focused on historical and real-time analytics for Fortune 500 companies. Next to my work at Bottlenose I'm also working part-time as Senior Data Scientist at OThot, where we try to harness the power of predictive analytics to improve business decisions for our clients.

I obtained my M.Sc. and B.Sc. in Computer Science from Delft University of Technology with minors in Psychology and Philosopy (at Leiden University). In Delft I continued pursuing a Ph.D. in Machine Learning.

Two years into the Ph.D. program I decided to leave university and join startup Wakoopa in Amsterdam (acquired in 2014) to build their recommender system. This valuable experience inspired me to found my own startup Newcope, a platform for predictive analytics of virtual goods. Newcope got seed funded by Y Combinator, which started of a roller coaster adventure in the heart of Silicon Valley, where I became part of the YC alumni network. After Newcope and freelance work, I joined the aforementioned company Bottlenose, where I continue to work on predictive analytics and scalable big data solutions.

My main interest is Data Science with a special focus on Machine Learning, Predictive Analytics and scaling out to handle big data.


While my primary focus is on Data Science, I'm also an experienced all-round web-developer (Node.js and Ruby on Rails).


Besides software development I'm also interested in advisory roles and business strategies. As a founder of a Y Combinator startup and Chief Architect of the fast growing company Bottlenose, I had my fair share of the emotional rollercoaster that every entrepreneur goes through, which are valuable experiences I love to share.
