I'm an eCommerce strategist based in London with 15 years across platform architecture, international expansion, and commercial strategy. Currently a consultant at Vervaunt, a London-based eCommerce consultancy and Shopify Plus Platinum Partner, where I work on enterprise replatforming, tech stack strategy, and international growth for fashion, beauty, and lifestyle brands.

My work sits at the intersection of technical architecture and commercial performance. I'm as comfortable evaluating data schema and metadata structure as I am conducting TCO analysis or translating KPI frameworks into C-suite reporting.

I've worked in-house running the channel, agency-side delivering it for clients, and now advise on how brands should think about it strategically. The combination changes what you notice. That range tends to surface problems, and solutions, that a single track doesn't.
