Madalyn Parker is a Senior Software Engineer with 11 years of experience building accessible, user-focused web applications and developer tooling. Based in Ann Arbor, she has delivered front-end and full-stack features at Microsoft and contributed major UI and accessibility improvements to high-profile open source projects like HashiCorp Vault and Gatsby. She led accessibility at Gatsby—creating company-wide training, auditing patterns, and screen-reader improvements for client-side routing—and has a track record of turning complex requirements into elegant, usable interfaces. Madalyn combines pragmatic engineering (rapidly learning Ember, building dynamic UIs) with strong advocacy for inclusive design and developer ergonomics. Her GitHub work shows a focus on practical UI enhancements—onboarding wizards, masked inputs, and WCAG-driven changes—that make security and performance-oriented projects more approachable. Off the keyboard she’s energized by live music, coffee, and the demands of her pet rabbits, which keeps her curiosity and empathy front-and-center.
