Ownership of decisions, teams and delivery.
I have worked across internet products, ecommerce and marketing since 2008. I founded D BLOK to take direct ownership of companies’ growth and marketing problems.
In brief
I began my professional career in internet products and ecommerce in 2008. I moved into technology and digital business before completing my mechanical engineering degree. Growth, performance marketing, analytics, product, CRM and marketing technology then developed along one career path.
As a founder, I built companies and products; at major brands, I held leadership roles. I managed remote teams across different countries, built a new market category from the ground up and established departments for companies at critical stages of growth.
I have helped professionals develop and take on broader responsibilities. Today, I use that experience as a Fractional CMO and advisor to solve problems across decisions, teams and execution.
