Hi! I'm Jack Zhang, an independent developer and global sourcing agent based in China.

Over the past few years, I've bridged global buyers with top-tier Chinese manufacturing hubs, from Shenzhen's electronics ecosystem to Yiwu's world-famous commodity markets.

As a full-stack developer, I also create modern web applications and SaaS products, aiming to ship 100 useful digital products under my '100 Sites Project'.
