I currently work on the WebGPU & WGSL team, helping develop next generation graphics APIs and shading languages for the web. I primarily work on the shader side of things, but also do a significant amount of work supporting infrastructure for the team and fuzzing related tasks.Over the last decade+ I have worked on a variety of teams and projects, which are detailed below.I started @ Google, working on Chrome & ChromeOS.I worked on a variety of projects while part of the Chrome team. This included device bring up of new hardware platforms, development & maintenance of power management, improving low level graphics performance, and improving touch UI support. I was directly involved in the efforts for the Chromebook Pixel and the Samsung ARM Chromebook, as well as general support for other devices.While Google owned Motorola, I worked at their Waterloo office on user authentication projects for Android.Upon returning to Google I worked on improving internal and external developer's experience with Google's iOS SDKs. This included building generalized infrastructure to support developing, building, and distributing our SDKs as well as some work at the APIs for certain projects.After this I worked on the iOS experience for Google Wifi, OnHub & Chromecast devices. Specifically this involved app side work related to the Home and Wifi apps, as well as build infrastructure and other developer productivity related tasks.I next returned to the Chrome team, working on the PDFium open source project. PDFium is the PDF library used by Chrome, Android, and other products for rendering PDFs. My work included significant code cleanup, fuzzing, feature work, and engineer productivity tool development.After the PDFium team's presence in my local office wound down, I have transferred to working graphics tooling. Originally started working on SPIR-V support and then transitioning to the WebGPU/WGSL efforts.

I worked on dealing with the fact that people hate entering passwords. My work focused on alternate authentication projects for mobile devices. Tasks involved with this included integrating new system services with Android's framework, implementing UI code/applications, and making sure what we were doing played nicely & securely with the rest of the system.

Developed device drivers and low level control software for embedded PowerPC products. Also worked on cataloguing and resolving various external software licenses used on products.

Worked on a combination of marking, running labs/tutorials, and sitting at the CS student helpdesk.

Refactored and optimized build chain for EPRNMR software tools. Removed legacy support to gain order of magnitude improvement in performance. Actively worked on bug fixes and other code improvements.

Assisted in student experiment labs and marked student lab reports.

Assisted lecturers by running student tutorials and marking. Occasionally had shifts in the student help centre

Worked on developing Debian packages and related scripts for the GNU tool chain for RTEMS.

Designed and implemented new orbit control system for facility based on RTEMS.
