Portfolio

  • Glasgow Haskell Compiler (GHC) (contributor). The flagship compiler for the Haskell programming language. Contributed to GHC’s support for metaprogramming, including deriving and Template Haskell.
  • blank-canvas (co-maintainer). A Haskell binding to the HTML5 <canvas> API, which allows for graphical web applications to be written in Haskell.
  • HERMIT (contributor and tester). An interactive Haskell compiler plugin that allows a user to apply code rewrites to make the process of high-assurance software development easier. HERMIT applies several semi-formal modeling techniques such as the worker/wrapper transformation.

Software skills

  • Proficient in Haskell, C, and Java. Familiar with Android, C++, JavaScript, Liquid Haskell, Standard ML, and Scala.
