My name is Sebastian Aaltonen. I have been writing graphics code for 30 years.

I shipped my first 3d accelerated game in 1999. Since then I have been working with almost every gaming console generation (Nokia N-Gage, Nintendo DS/Switch, Sony Playstation/Portable, Microsoft Xbox) and every PC graphics API (DirectX, OpenGL, Vulkan).

For the last 4 years I have been building a new renderer for HypeHype targeting WebGPU, Metal (Mac & iOS) and Vulkan (Android).

During my career I have been building several Ubisoft internal engines, optimizing Unreal Engine 4 and leading the Unity DOTS graphics team. I am a member of the Vulkan Advisory Panel and an Arm Ambassador.
