Portrait of Rogelio Moreno Guinea

Before working with datasets, I spent years working with another kind of complexity: regulation, risk, clients, negotiation, and business decisions.

Data analytics adds a technical layer to that experience, helping me frame better questions, test evidence, and communicate what deserves attention.
