China Sourcing Expert | OEM Factory Verification | Reverse Sourcing

Most clients come to me when they're unsure who they're really working with — whether a supplier is a genuine manufacturer, what a factory can realistically produce, or where the risks are before placing an order. At that point, finding more suppliers rarely solves the problem. The real challenge is verifying capabilities, understanding risks, and making sourcing decisions based on facts rather than claims. Since 2017, I've helped 1,500+ clients across 50+ countries identify qualified manufacturers, verify suppliers, trace products back to their actual OEM/ODM source, and reduce sourcing risk before production begins. What I help with Factory vs. trading company verification Reverse sourcing and OEM identification Supplier qualification and risk assessment Production capability evaluation OEM/ODM supplier development MOQ, pricing, sample, and feasibility review Factory-side coordination and sourcing support My background in manufacturing operations helps me evaluate suppliers from a production perspective, not just based on online listings and sales claims. I work entirely through written communication with clear documentation and structured updates. If you already have a supplier, factory, product, Alibaba link, or quotation you're unsure about, feel free to send it over. I'll provide a clear assessment of the risks, opportunities, and practical next steps.
