Since I started programming when I was 11, I wrote the SNES emulator "SNEqr", the FastNav mapping component, the Enhanced C# programming language (in progress), the parser generator LLLPG, and LES, a syntax to help you start building programming languages, DSLs or build systems.

My overall focus is on the Language of your choice (Loyc) initiative, which is about investigating ways to improve interoperability between programming languages and putting more power in the hands of developers. I'm also seeking employment.
