About Me

Profile Photo

I'm a software developer from The Netherlands, working at GitLab as a Staff Backend Engineer. Outside of the work I do for GitLab, I'm interested in the development and theory of compilers, virtual machines, garbage collectors, and programming languages. I primarily work with Ruby, Rust, and at times C.

You can contact me via Email, Twitter, or Reddit; though I prefer Email. You can also find me on GitLab, GitHub. Please do not contact me if you are a recruiter.

My GPG public key is EB691AC9 registered using Email address yorick@yorickpeterse.com. Other keys registered on my name are no longer in use.
