At OSANG LLC, I serve as total channel owner for Amazon Seller Central, directing P&L and growth roadmaps. I’ve driven 35% year-over-year marketplace revenue growth and improved profitability by 28% through media planning and alignment across Korea HQ and U.S. HQ teams.

At CONTIXO, I managed an $18M+ multi-channel revenue P&L across Amazon, Walmart Marketplace, TikTok Shop, and Shopify. I spearheaded the zero-to-one TikTok Shop launch and helped cut Amazon advertising ACoS by 25% year over year.

At THUNDER COMMERCE, I directed marketplace strategy across 15+ accounts and scaled ROAS by 30% across more than 1,000 campaigns. I also optimized 800+ product listings and recaptured more than $20K in lost FBA reimbursements.
