Vetted and demonstrated React as a new frontend library that had significant advantages over Angular at the time. It was a solid choice agreed to by the rest of the web team. Implemented CSS modules and worked with the UX designer to create base theme variables and component styles. At some point moved the CSS components to styled components for react. I must have re-skinned the sansar website, and all of it's many subdomains and landing pages about a hundred times before it's final iterations at Linden Lab.
