Data engineerSan Francisco
I build data systems people can trust, and I’m starting to build products of my own.
For the past four years I’ve worked on data platforms at Visa and Meta: pipelines that process millions of records a day, and the validation that catches problems before anyone downstream sees them. I studied finance before data science, and I’m most interested in where engineering, AI and entrepreneurship meet.
I believe in taking risks and iterating.
