Data science & strategy

Turning rigorous analytics into bold decisions.

I build predictive systems, experiment with statistical methods, and publish the lessons that emerge along the way. This space captures the work that shapes my practice.

Who I am

I care about transforming how analysis informs the future.

I am a young innovator focused on doing different things to achieve new results. I believe that the future can be better than the past for those who care. I care about creating, transforming and improving the way analysis is done.

My name is Julio Sotelo. I hold a Master in Predictive Analytics from DePaul University in Chicago. I perceive excellence as the only option and that drives everything I do, even when I’m having fun (for instance: I won second place in Chicago’s Transamerican Triathlon last year and qualified for the US National Championship 2016 and have 3 podiums in the last year '24-'25).
