Jack Zhang

I’m a Product Certification Manager with experience providing international certification and customer service for potential clients—introducing services, answering inquiries, preparing quotations, and following up. I’ve successfully converted 3 clients and supported them through the international certification process with 100% customer satisfaction, and I independently developed certification training courses that helped 2 clients pass exams and obtain official certificates. I also contribute to standardization by drafting certification proposals and creating standardized documentation templates.

Alongside certification work, I’ve driven brand-building through content operations and channel management, including writing and publishing 20+ professional WeChat articles that increased readership by 30% and achieved a customer conversion rate of over 50% among 70+ inquiries, plus running Rednote posts that generated 6 client inquiries. I maintain official web presence by registering domains, completing ICP filing, and ensuring timely updates, and I bring bilingual communication strength through translation and consecutive interpreting—earned recognition from leaders and guests during project introductions and business negotiations.
