Summary
Rebecca Miller-webster is a seasoned software engineering leader with 13 years of experience building developer tools and client apps, currently directing Copilot Workspace and Codespaces at GitHub. She has a track record of turning around complex, high-stakes organizations—most recently leading a data center deprecation that saved GitHub $4M annually and launching Copilot features that improved adoption, ARR, and PR cycle time. Rebecca combines hands-on product and platform experience (mobile, desktop, CLI, Codespaces, Actions) with strong people leadership, having scaled teams rapidly and resolved deep cultural and delivery challenges. As founder and longtime leader of Write/Speak/Code she’s boosted diverse representation in tech and grown a volunteer community from dozens to thousands. Her background spans startups to large enterprises, shipping both user-facing apps and infrastructure while keeping an eye on measurable business impact. Based in Chicago, she pairs technical depth (MS in CS) with advocacy and systems-level thinking that surfaces non-obvious opportunities for product and organizational improvement.
