Jason Sher
eCommerce + AI/Automation Specialist
Product leader.
AI strategist.
Builder.
I've spent the last decade building in eCommerce and product across the US, Europe, and South Africa. I built and led the marketplace division at eComplete in Cape Town — lifting client revenue by an average of 60% — and ran the new-launches team at Berlin Brands Group, one of Europe's largest Amazon-native brand groups. Today I'm the founder of JS Labs, where I build agentic systems on a Next.js + Supabase + Vercel stack to automate the operational work that normally drowns marketplace teams.
