What I'm looking for

I'm looking for product analytics work where I can use A/B testing, retention and funnel analysis, and Python automation to turn complex data into product decisions.

I'm working on subscription e-commerce product analytics, partnering with CRO and retention teams to run A/B tests, evaluate hypotheses, and build Python tools. My retention-model research reduced A/B test duration by 37% without sacrificing quality.

Before product analytics, I advised clients at KPMG, EY, and Deloitte on complex international tax decisions. I bring 3+ years of experience turning messy multi-source data into quantified recommendations, automated workflows, and executive-ready reporting.
