About Wilfredo J. Molina
I trained as a mathematician, which means I learned to sit with hard things until they become clear. That discipline has carried across everything I\'ve done since: research, machine learning, infrastructure, software. The domain changes. The work is the same. Understand the structure together. Find the solutions.
