More about how I work

I grew up in the Bay Area asking why systems work the way they do, who they serve, and how they could be better. That curiosity led me through math, computer science, business, and data science.

  • Research: market sizing, competitive intelligence, public filings, and executive-ready synthesis.
  • Analysis: modeling, experimentation, statistical thinking, feature engineering, and reproducible workflows.
  • Product: user needs, information architecture, MVP definition, and translating evidence into decisions.
  • Business: operating metrics, revenue and cash-flow analysis, budget variance, and business-model comparison.

Open to product, data, and strategy roles.
