I am currently a consultant working with Well-Typed LLC. In this capacity I am lucky to be able to spend much of my time working on the Glasgow Haskell Compiler
Outside of work I contribute to a variety of open-source projects, including the Glasgow Haskell Compiler, rustc, the Haskell Chart library, and matplotlib. I have several patches in the Linux kernel, and a numerous contributions across a variety of smaller Haskell libraries. I occassionally also dabble in embedded systems development and tinker on variety projects of a more mechanical nature.
