Personal Projects
Language Designer, Lead Developer
  • A language similar to JSON but designed to be pleasant to edit for game designers, and easy to extend for gameplay programmers
  • Designed language syntax, wrote the reference implementation in C++, wrote extensive unit tests and comprehensive technical documentation
  • The language syntax supports key/value maps, arrays, type hinting, numbers with units, timestamps, comments, and custom lexical expressions (for embedding math expressions or small snippets of game logic into configuration files)
  • Wrote syntax highlighting extensions for Sublime Text and Visual Studio Code
University of Puget Sound Computer Science Capstone Project
  • A game using Unreal Engine 4 that taught basic programming concepts in a visual way by having the player enter code into in-game computer terminals
  • Each in-game computer terminal had an embedded Python subinterpreter thread with APIs for controlling game mechanics (for example, typing door.open() would open a door connected to that terminal)
  • The in-game code editing UI was powered by Chromium Embedded Framework
