Are you looking for a marketplace specialist who can do more than simply upload products and update spreadsheets? I help brands and retailers build, optimize, troubleshoot, and maintain accurate marketplace catalogs — from product onboarding and catalog setup to listing optimization, product content, validation, and ongoing marketplace operations. I’m an E-commerce Operations & Marketplace Specialist with 10+ years of operations experience and 5 years of hands-on eCommerce marketplace experience, with a strong focus on Mirakl, Mirakl Connect, and Shopify.

WHAT I CAN DO FOR YOUR MARKETPLACE ● Product Listing & Optimization Create, update, and optimize product titles, descriptions, attributes, specifications, categories, pricing, inventory, and other marketplace fields. ● Mirakl & Mirakl Connect Manage marketplace catalog workflows, seller and brand onboarding, product uploads, offer data, validation, and marketplace maintenance. ● Catalog Management & Cleanup Transform incomplete, inconsistent, or unstructured product data into organized, accurate, marketplace-ready catalogs. ● Bulk Product Uploads Work with Excel, CSV, TXT, and marketplace templates for high-volume product uploads and catalog updates. ● Attribute & Category Mapping Map product information to marketplace-specific categories, attributes, mandatory fields, and taxonomy requirements. ● Catalog Error Troubleshooting Investigate validation errors, rejected products, missing attributes, incorrect data, feed issues, and other listing problems. ● Product Content & Images Prepare product images, resize images, create marketplace-ready visual assets, build size charts, and improve product presentation. ● Brand Copy & Promotional Content Create or update brand copy, product content, campaign messaging, and promotional marketplace content. ● Product Data QA Review SKUs, product identifiers, attributes, variations, pricing, inventory, images, and content for accuracy and consistency. ● Marketplace Audits Review existing catalogs to identify missing information, incorrect attributes, content gaps, listing inconsistencies, and other catalog issues.

WHY WORK WITH ME? ✔ 10+ years of operations and BPO experience ✔ 5 years of hands-on eCommerce marketplace experience ✔ Strong Mirakl and Mirakl Connect background ✔ Enterprise retail marketplace experience ✔ Product catalog and listing expertise ✔ Experience working with complex product data and marketplace requirements ✔ Strong attention to detail and data accuracy ✔ Marketplace error and catalog troubleshooting experience ✔ Product content, images, and size-chart creation ✔ Seller and brand onboarding experience ✔ Team leadership and training background ✔ Clear communication and structured workflows I don't view marketplace work as simply uploading products. A successful listing needs to be accurate, complete, properly categorized, visually presentable, compliant with marketplace requirements, and easy for customers to understand.
