Jason Sher
eCommerce + AI/Automation Specialist
Product leader.
AI strategist.
Builder.
I've spent 10+ years scaling marketplaces across the US, South Africa, and Europe — most of it on Amazon and the marketplaces orbiting it. 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.

Autonomous Catalog Agent
Agentic system that monitors marketplace listings, detects content drift, and pushes corrected copy and imagery back through Amazon SP-API. Compresses catalog QA from days to minutes.
Cross-Border Marketplace Launch
Playbook for taking a US-native brand into UK and SA marketplaces — listing localization, compliance, fulfillment, and pricing strategy codified into a repeatable launch motion.
Repricing Engine
Daily competitive repricer across thousands of SKUs with rule-based guardrails. Tracks margin floor, buy-box position, and competitor velocity to keep pricing honest without eroding profit.
Catalog Health Dashboard
Internal tooling for marketplace ops teams — surfaces broken listings, missing variants, and policy violations before they cause suppressions. Next.js + Supabase, Vercel-hosted.
Let's build something together.
I'm always interested in hearing about new opportunities, challenging problems, and interesting projects.
