ABOUT

Marketplace specialist.

I help brands grow on Amazon, Shopify, and DTC, backed by 10+ years of marketplace results across the US, Europe, and South Africa: an 83% portfolio sales lift in 8 months, a 60% average client revenue increase, and launches across 1,000+ SKUs. Today I run e-commerce for the Col'Cacchio franchise and build through JS Labs.
