Senior Software Engineer with 17+ years building large-scale web applications and developer platforms across enterprise and high-traffic consumer products, including Workday, Houghton Mifflin Harcourt, and CarTrawler. I focus on the intersection of frontend architecture and developer productivity—design systems, CI reliability, and feature-toggled rollouts. Most recently I designed and rolled out an AI-assisted development framework across a 50+ engineer organisation, including coding standards and reusable agent workflows that reduced incident triage from manual investigation to roughly five minutes. I enjoy ambiguous product spaces: bringing structure to problems without a clear shape and moving teams from idea to reliable production systems.…Senior Software Engineer with 17+ years building large-scale web applications and developer platforms across enterprise and high-traffic consumer products, including Workday, Houghton Mifflin Harcourt, and CarTrawler.
