Michael Keegan

I am a senior full-stack engineer with extensive experience delivering large-scale, high-impact products at companies including Chewy, Google, and Constant Contact. I focus on building performant, accessible, and user-centric systems using React, TypeScript, Node.js, Python, and Java.

At Chewy I led the end-to-end design and development of a VetCare platform, built appointment scheduling and online check-in features, and designed microservices that achieved 99.98% uptime while scaling to tens of thousands of concurrent users. I integrated third-party APIs and deployed cloud-native architectures on AWS and Kubernetes with HIPAA considerations.

At Google I contributed to Immersive View for Routes, optimizing frontend rendering and backend pipelines to deliver smooth 60fps 3D previews and sub-200ms response times, while integrating ML-driven overlays. Across roles I’ve improved performance, reduced UI lag, and cut operational overhead through automation and infrastructure improvements.

I am a collaborative mentor and cross-functional partner who establishes CI/CD and test automation best practices, drives accessibility compliance, and helps teams ship reliable, production-quality features rapidly.
