About

Hi, I’m Rainer — a tech entrepreneur and engineer from Estonia.

I co-founded Ready Player Me, where I served as CTO from 2014 to 2025, before the company was acquired by Netflix. Today I’m Director, Games Engineering at Netflix, building products at the intersection of games, developer tools, avatars, and AI.

I write here about the technical work I do and the tools I build for myself, with the occasional detour into coffee, productivity systems, or whatever I’m currently exploring.

You can see more of my work history or get in touch.
