eCommerce Consulting

Experimentation

I help eCommerce brands scale their A/B testing programs from random experiments to systematic growth engines. With over 1.500+ tests run across 50+ brands, I transform testing chaos into predictable revenue growth.

Growth

Beyond testing, I build complete growth systems that compound over time. From conversion optimization to retention strategies, I help ambitious brands unlock their next phase of growth.
