Josh Ferge is a Senior Software Engineer based in New York with a decade of experience, currently building developer-facing features at Sentry. He’s a pragmatic full‑stack contributor to the well-known getsentry projects, driving end-to-end replay work—adding sequence IDs, session models, new endpoints and even compression in web‑worker builds to make replay streams reliable and efficient. Earlier roles show entrepreneurial product chops: he led software at unspun (novel fit algorithms for custom apparel), was the first non‑founder engineer at Augur building big‑data and fingerprinting systems, and co‑founded Cherish, shipping the CU Bus Tracker app with over a million sessions. Josh combines backend systems, SDK work, and documentation improvements to move features from spec to production while keeping developer ergonomics front of mind.
