About

Sebastian Himmer

A bit more context

I started out making games in Roblox as a kid, then moved on to Unity, where I worked as a gameplay and tooling programmer on both games and internal applications. After that I switched to C++ and found what I really enjoy: building custom engines. I still find gameplay work fun, but somewhere along the way engine and tooling became the side that pulled me in the most.

Let's talk

I'm currently studying and will be looking for an internship starting September 2027. If you want to keep in touch or talk about any of my projects, don't hesitate to reach out.
