Summary
🤩
Rockstar🎓
Top SchoolDan Miller is a software engineer with 11 years of experience building developer tools, backend systems, and performant web platforms, currently at Figma after four years helping ship Replay.io’s record-and-replay debugger. He’s comfortable across the stack—having led early product growth at Tilt (employee #1) by building cross-platform file watching, Kubernetes/Bazel integrations and a SaaS backend, and later improving large-scale search and platform reliability at Etsy and Upserve. At Replay he focused on frontend UX and debugging features (including mixpanel-driven behavior tracking and robust WebSocket error handling) for the open devtools repo used by web debuggers. He combines production-facing engineering with customer-facing roles like support and mentorship, and has a habit of pairing deep systems work (HHVM performance, caching and edge-side rendering) with practical product shipping. Based in Seattle, he pairs a strong operational background—early sysadmin and infrastructure work—with a curiosity for languages and systems gained during a Recurse Center stint working on Haskell and low-latency multiplayer techniques.
