Gosha is an incredible engineer. Easily one of the most thoughtful people I have ever worked with across Pinterest and Gumroad, and whomever gains them will be very lucky. Our front-end architecture improved dramatically, in large part due to Gosha, as we helped plan and lead our migration to React, TypeScript, and more.
