About
I'm Geng Wang, a freelance web and mobile developer. I build products from the first idea through to launch.
My story
Before working independently, I spent eight years as a software engineer at Tencent and NetEase. I worked on products at a scale where reliability matters every day, including a music live-streaming app with over 50 million monthly active users.
I went independent to work directly with founders and businesses, closer to the decisions that shape a product. For Cellar Twenty One, I built a custom champagne inquiry website. For Appvertise, I built the iOS and Android apps, web admin panel, and Firebase backend.
I bring the engineering discipline of large product teams and the direct communication of a solo developer. You work with the person building your product, from the first conversation to delivery.
