GengWang Z.

Senior Web & Mobile App Developer | 8+ Years

I've been building mobile apps for over 8 years. I cut my teeth at top Chinese tech companies like Tencent Music and NetEase Games. That's where I learned how to ship high-performance Android apps and smooth cross-platform experiences using React Native and Flutter. I'm also a full-stack developer, so I won't just throw code over the wall. I understand the whole pipeline, including the backend with Node.js. I've shipped apps across Google Play, iOS, and WeChat Mini Programs. You can check out my work here: a custom suit website I built, the Padel Spot app for Android and iOS, and a WeChat Mini Program for Paijitang.
