Working on WebAssembly tooling and standards as part of the v8/Chrome team. Primary maintainer of Emscripten, the toolchain used to bring C/C++ applications to the Web. Contributor to the WebAssembly LLVM backend. Creator and maintainer of the WebAssembly linker (wasm-ld), which is part of the LLVM project. Many contributions to wabt and binaryen, two of the most popular tools for WebAssembly manipulation and optimization.

Active in the WebAssembly standards process and champion of two proposals that are now part of the WebAssembly standard: Memory64 (which enables access to memories larger than 4GiB) and Extended Constant Expressions (which allows for more expressive initialisers).

Prior to 2015, worked on the Native Client (NaCL) toolchain and SDK. This was the native code sandbox in Chromium the preceded WebAssembly. Primary maintainer of the naclports project, comprising over 200 ports of open source projects to Native Client.

Ideaworks3D was a technology company and game development studio that brought many AAA game titles to mobile including Call of Duty, Metal Gear Solid, Tony Hawk's Pro Skater, Tetris, Game of Life, Tomb Raider, Need for Speed and The Sims. We won several industry awards including the two BAFTAs.

Led development on the core runtime of the Marmalade SDK. This was a platform abstraction technology which powered many mobile games of the time. The technology allowed a single native binary to be executed on any operating system. This enabled apps to be written once, against a standard API and deployed to all platforms without porting or recompilation. Targets included iOS, Android, WebOS, Symbian, Winmobile, and more.

Lead engineer on Airplay Online, the network protocol and server technology that enabled many successful games both in-house and third-party. Developed fast, scalable server application using C++/Linux/pthreads and utilising embedded Python or Java for highly customisable online game behavior. Developed and maintained the Airplay Online server cluster.

Worked primarily on the XOE (previously PocketLinux) project, an operating system for PDAs and other resource constrained devices. XOE was open source, build on Linux, Java, and XML, with the goal allowing app developers to write as much as possible, including application logic and presentation layer, in XML. Work included Linux kernel programming, and JVM internals. Also responsible for building cross compiler toolchains and creating embedded Linux images.

Many of the ideas we developed for PocketLinux are visible today in the Android OS, which bears a striking resemblance.

Worked with customers to bring realistic physics to the next generation of games. Involved coding in C/C++ targeting next generation gaming platforms. Created and maintained Linux port of MathEngine products. Worked on one of the Japanese PS/2 launch titles.
