Josh Ferge is a Staff Software Engineer based in New York with 11 years of experience building full-stack systems and developer tools, currently leading replay-related features at Sentry. He combines backend API and model design with front-end documentation and SDK work—contributing to Sentry’s popular sentry-javascript SDK, docs, and core backend to improve session replay, compression, and replay stream ordering. Prior roles span startups and scale-ups where he led product-focused engineering (including a custom-fit apparel platform and early growth at Augur) and shipped mobile and web products that reached significant user scale. Comfortable across Node.js, backend services, and frontend UX, he has a track record of turning ambiguous problems into production-ready systems and automations. An early founder and frequent open-source contributor, he pairs pragmatic engineering with a product-minded instinct for observability and developer experience.
