Summary
🤩
RockstarJay Phelps is a Senior Software Engineer with 14 years of experience building resilient front- and back-end systems, currently based in the Austin metro area and working at Netflix. He combines deep framework expertise—contributing to high-profile open-source projects like Ember.js and Babel—with low-level toolchain work such as WebAssembly Binaryen, showing fluency from UI helpers to compiler flags. A founder and former CTO, he blends product-minded leadership with hands-on engineering, having led build systems, routing improvements, and developer ergonomics across multiple teams. His open-source core-decorators library and contributions to redux-observable demonstrate a knack for improving developer experience and async flows. Colleagues describe him as the kind of engineer who both refactors legacy code thoughtfully and adds subtle features (like Router auto-location) that meaningfully smooth day-to-day workflows.
