What I'm looking for

I’m looking for an e-commerce operations role where I can scale marketplaces, improve digital shelf accuracy, and drive growth through listing optimization and social commerce/affiliate programs—backed by strong product data management.

I’m an E-Commerce Operations Specialist with 5+ years of experience managing 10,000+ SKU catalogs across Shopify, Amazon Seller Central, Rithum, and TikTok Shop. I specialize in Product Data Management, Digital Shelf Auditing & Optimization, Listing Optimization, Site Merchandising, and TikTok Shop Operations—turning messy catalog data into accurate, high-performing storefront experiences.

Most notably, I spearheaded the concept, launch, and growth of Crazy Dog T-Shirts' TikTok Shop, scaling the channel to approximately $1.3 million in monthly revenue while improving catalog accuracy and operational efficiency. I execute product launches, merchandising initiatives, and promotional updates across multiple ecommerce platforms, while analyzing catalog performance and workﬂows to continuously improve discoverability and data quality. Previously, I founded and operated a concierge healthcare services business where I built systems and operational workﬂows from the ground up.
