* Created & implemented operational plan for new application frameworks in PlayStation experiences, to improve performance & stability, forming the basis of PlayStation 5.* Created and edited content to transition 400+ developers across 5+ geographies to said new application frameworks. * Led transition from inception of the software stack in August 2017, into prototyping, iterating on and re-communicating architectural and performance guidance, to the 1.0 deliverable milestone that included 40+ applications in February 2020.Contributed to React Native, React Navigation, and React Native Windows, along with related OSS libraries and tooling. On any given week I worked in JavaScript, C#, and C++17 across Windows, Mac, Linux, and unreleased hardware platforms. Used Intel vTune, Razor CPU profiler, and cachegrind to profile and drive optimizations that contributed to a magical, seamless user experience.Designed and implemented semi-automatic telemetry for all React-based products, to align metrics across app portfolio (console, mobile, & web) and the UX design system, with input from Business Intelligence & Global Store Operations Site lead for the the LGBTQ employee group, volunteering for and co-organizing inclusive events at GDC, San Francisco Pride, Los Angeles Pride, HRC, and GLAAD for #AllTheGamers and #AllTheCreators.

* Led complete rewrite and engineering strategy reboot for BlueJeans' Enterprise Windows offering, encompassing the vast majority of revenue flowing into the company. * Founded new team comprised of new NRE, FTE, and OSS team members.* Increased developer productivity, service availability, and collaboration with external partners by transitioning source control, continuous integration, and deployment services from on-premises to cloud (GitHub, CircleCI, etc)* Bootstrapped port of React Native to Windows 7 and 8 by contributing JavaScript, C#, and C++ code to various open source projects. * Delivered in-depth technical presentations on shipping and supporting product with React Native Windows at .NET and React Native user groups and conferences around the world.
