At Valve I'm a recognized senior leader on the Steam team. My primary work is as an individual contributor working mostly in C++, TypeScript, and PHP on a variety of Steam related projects. Engineers at Valve also take on roles including Product Management, Architecture, Design, and Team Leadership and I have experience in all these areas. I have been a key contributor to the success of Steam both at a product level and at a technical level as we have grown and scaled out massively since I joined the company in 2006.I led the efforts to develop our in-game overlay technology. I was a major contributor to porting most of Steam to PS3 for the launch of Portal2.I frequently work deeply on product and UI design alongside our designers. I was the architect of our next generation UI framework used in Steam Big Picture and our Source 2 game engine. I was a key contributor to the Steam refund policy and modernization efforts for Steam Support. This involved major organizational, business, and management work as well as work leading development efforts to improve our help request/ticketing functionality and tools.I led a complete overhaul of Steam voice chat greatly increasing quality as well as security and privacy for users.I have been deeply involved in moving UI both in-client and on the Web to a modern React based architecture. I have been a go to person for solving deep performance and scalability issues on Steam's C++ Servers, Web Stack, and in the Steam Client for the duration of my time at Valve.I'm never afraid to go deep technically and have worked on a variety of low level projects. One example is my work overhauling our C++ inter-server network communication layer to add threading and enable SSL encryption between all servers. A second example is building the low level x86 detours library and the D3D/OpenGL and input hooks necessary to make our Steam In-Game Overlay render in third-party games without modification.

At Klir I was responsible for development of all of the back-end systems which allowed us to provide a hosted solution for distributed network monitoring for clients around the globe. This backend work involved a large amount of C++ coding, Linux/Unix knowledge, systems level programming, multithreading, SQL, and client/server development. In addition to my primary work on the back-end I was also a major contributor on our front-end web application working in PHP, JavaScript, HTML, and CSS to create a rich Web 2.0 style web interface.
