Senior🎓
Top SchoolMichael Krotscheck is a Principal Engineer specializing in identity and access management with over two decades of experience designing cloud-based IAM solutions and 14 years in hands-on engineering roles. He blends strategic, cross-organizational architecture with pragmatic implementation—authoring RFCs, building consensus, and shipping features that impact both UI and backend services. Michael has led identity platforms at VMware and recently joined Zillow, bringing expertise in OAuth2, CORS, and SaaS/on‑prem integrations. A longtime contributor to OpenStack projects like Keystone and Horizon, he modernized front-end tooling and reinforced backend CORS middleware, demonstrating a rare mix of front-end polish and backend reliability. Trained as an architect with an MBA, he pairs design thinking and business strategy to make secure, maintainable systems easy to understand and operate. Known for tackling thorny multi-team problems, he also injects a bit of whimsy into otherwise serious infrastructure work.
