Hi, I'm Jonathan Au.

Two decades transforming complex technical problems into products people enjoy, from touch-responsive tablet UIs to cloud games that turn living rooms into multiplayer arcades.

01. About Me

Jonathan Au Profile Photo

I've spent two decades transforming complex technical problems into products people enjoy. From designing touch-responsive animations for Microsoft's first tablet OS to turning living rooms into multiplayer arcades with nothing but a TV and a few phones, the thread through my career is making sophisticated technology feel simple for customers.

At Amazon, I create gaming experiences that are fun, engaging, and effortless to dive into, removing the barriers that keep people from playing together. Before that, I owned personalization and engagement for Prime Gaming, shipping recommendation engines and A/B-tested features that measurably moved retention and conversion.

I'm currently investing in applied AI/ML, with recent certifications in deep learning, RAG, and generative AI from Stanford, DeepLearning.AI, and AWS.
