About

As a Product Manager at GitHub I lead product strategies across multiple teams, including: * Semantic search for GitHub Copilot (Blackbird). * Evolving commit signatures into Authentic Contributions. * Overall BCDR (Business Continuity & Disaster Recovery) product strategy and guidance. * Development leadership and product mentorship for npm, focusing on support and trust & safety escalations. My previous roles include being a product manager for web frameworks (Salesforce LWC) and contributing extensively to web standards and open source. I have served as a delegate at Ecma's TC39, co-edited ECMA-402 (the Internationalization API for EcmaScript), and been a lead maintainer for both Test262 (the official test suite for ECMAScript) and QUnit (a test framework used in projects like jQuery, Lodash, and Ember).
