TikTok Shop US Backend Setup Specialist

I am looking for a highly experienced TikTok Shop US specialist to help me fix and complete the entire backend setup for an established US brand. I am the 100% owner of all accounts and businesses involved and have access to all accounts and corporate documents. Current issues: • TikTok account @pimaprima is still linked to an old TikTok Shop/business setup and needs to be correctly unlinked/relinked. • My current US TikTok Shop has a Pre-KYC/KYB onboarding issue that needs to be diagnosed and resolved. • Business Center / TikTok account / Seller Center relationships need to be audited and correctly configured. • After approval, I need help setting up fulfillment / Fulfilled by TikTok (FBT) and getting the Shop fully operational. I am NOT looking for social media management, content creation, TikTok Ads, affiliate marketing or dropshipping. I need someone with proven hands-on experience troubleshooting TikTok Shop US Seller Center backend issues. Please apply only if you have personally handled: KYC/KYB verification issues, Seller Center account linking/unlinking, Business Center configuration and TikTok Shop fulfillment. In your application, please briefly describe a similar TikTok Shop problem you personally resolved.
