David Grayson

I do a lot of embedded programming and desktop software programming with C and C++. Ruby is my go-to scripting language. I can find my way around C#, Python, and a lot of other languages. I'm interested in things like Nix (the functional package manager), Qt, compilers, and the interfaces between operating system and application.

I work as an engineer for Pololu Robotics & Electronics.
