Seattle, Washington, US

• Title - Punch Club (Nintendo 3DS)
• Implemented a data-driven, data-oriented, component-based entity system to promote both fast iteration time and cache-friendly code and data layouts on Nintendo 3DS hardware.
• Put together a reusable game framework based on Engine Black to quickly provide the team with a basis for the port from Unity/C# to C++.
• Wrote a C# tool to convert from Unity’s YAML format to a simpler custom JSON format.
• Debugged, profiled, and optimized code after the move from C# to keep builds stable and scene transition times minimal.

Bellevue, WA, US

• Title - Guild Wars 2
• Implemented lightweight server-side movement validation to improve cheat report reliability and guide full physics validation toward suspicious clients.
• In response to designer requests, added features in many areas, such as physics-based player movement, combat systems, skills, scripting, and UI.
• As a member of the platform team, improved designer workflow and chipped away at technical debt in the codebase.

Seattle, Washington, US

• Title - Regular Show: Mordecai and Rigby in 8-bit Land
• Designed and implemented data-driven, component-based entity system to provide the flexibility required to quickly tweak and iterate on gameplay.
• Designed and implemented event system to enable loosely-coupled inter-component and inter-entity communication.
