About

20 years ago, I watched Jackie Chan do his own stunts and thought: "I want that discipline." So I started training. Taekwondo first, earned my black belt. Then kickboxing. Now I'm a trainer myself, teaching the next generation what took me two decades to learn: show up, stay humble, keep going. That same mindset shaped my career. I fell into data governance the way most people do, by seeing what happens when nobody owns the data. Chaos. Mistrust. Decisions based on gut feeling instead of facts. Today I help organizations fix that. At Adastra, I design governance frameworks, build data strategies, and make sure people can actually trust what they're looking at. What I bring: Hybrid governance architectures Data quality & metadata management Translating technical complexity into business clarity What drives me: The same thing that kept me training for 20 years: Discipline, curiosity, and the belief that "good enough" never is.
