Over the past 10 years, I’ve built a deep, hands-on understanding of how every part of an eCommerce operation fits together, from website UX, retention marketing (email/SMS), and CX optimization to backend systems like ERP, shipping, and software infrastructure.
While I’ve worked across the full stack, my focus is clear: helping DTC and B2B brands grow smarter, leaner, and more profitably through eCommerce strategy that actually works.
