What I'm looking for

I’m looking for consulting, fractional Head of Ecommerce, in-house Amazon Brand Manager, or strategic partnership opportunities with ecommerce businesses ready to scale systematically.

I build and run ecommerce operations for Shopify and Amazon brands through Matthew & Helen, combining SEO, PPC, conversion optimization, and AI-connected workflows. Over eight years, I’ve built more than 100 Shopify stores, including 15+ Shopify Plus stores, from concept through launch and post-launch support.

I’ve increased Google Ads ROAS from 600% to 1400% in six months, generated 512% sales growth through content, ads, and SEO, and grew organic revenue 45% in 90 days. On Amazon, I raised ROAS from 3.9 to 7.1 while cutting TACoS from 20% to 11%, and improved a top-selling bed and mattress listing’s conversion rate from 1.3% to 5.7% in 90 days.

I scope complex Shopify automations, brief development teams, and lead remote specialists across SEO, PPC, design, content, data, and marketplace management. I’m available for consulting, fractional Head of Ecommerce work, Amazon Brand Manager roles, and strategic partnerships.
