Gumroad

Gumroad is an ecommerce platform that allows indie creators to go from zero to accepting payments in no time.

My involvement in Gumroad includes:

leading transition to well-typed codebase, away from untyped JavaScript to TypeScript
leading transition to React, away from an outdated jQuery and flight.js stack
both of which enabled faster and more condfident delivery of new user-facing features

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.
