What I'm looking for

I'm seeking a remote U.S.-based role in e-commerce, marketplace operations, PPC, or Amazon and Walmart brand management, where I can use data-driven listing, advertising, inventory, and marketplace optimization to drive measurable growth.

At Platinum Enterprising, I manage 20 Amazon ASINs generating approximately $400K monthly in gross profit and 8,000 monthly units sold. I improved a key ASIN through A/B testing and listing optimization, increasing sales by 20%, lifting conversion from 15% to 22%, and reducing ACOS by approximately 30%.

I've grown Walmart account sales 3x in under two months through listing-quality and PPC improvements, and I audit agency-managed Amazon campaigns with about $100K in monthly spend to identify inefficiencies. Previously at Some12Trust, I managed Amazon PPC, SEO, listings, FBA operations, product research, and inventory for 10 ASINs generating up to $20K monthly in revenue.

My background also includes procurement, demand planning, manufacturing, and cross-functional operations across thousands of SKUs. I use Helium 10, Sellerboard, advanced Excel, Amazon Seller Central, and Walmart Seller Center to turn marketplace data into stronger rankings, traffic, conversion, and profitability.
