Senior Data Engineer  /  Systems Thinker  /  Explorer

Building systems that connect data, technology, and real‑world outcomes.

I design and build large-scale measurement and analytics platforms and write about the systems, ideas, and trade-offs along the way.

01About

I build systems. I think in systems. I explore systems.

I'm a Data Engineer with seven years building large-scale measurement and analytics platforms, spanning retail media, advertising, telecom, pharma, and public health research.

I enjoy problems where business, technology, and human behavior intersect. The messiest ones, the kind that span teams, disciplines, and systems, are the ones I find most interesting.

Outside of work, I write about technology, read widely, and think about what it means to build things that matter. Working toward technology leadership and, eventually, building something of my own.
