Rockstar🎓
Top SchoolMike O'brien is a seasoned cloud and infrastructure technologist with 9 years focused at AWS and a multi-decade track record in systems, network management, and product engineering. At AWS he led DevOps and Software Assurance for large developer teams and built an Automated Security Response package to remediate Security Hub findings, blending hands-on coding (TypeScript, Python, CDK) with operational security. His background spans solutions architecture, technical account management, and large-scale migration planning—most notably contributing to a 2,500+ server datacenter-to-cloud migration and enterprise cloud operations platforms. Mike pairs deep legacy systems experience (mainframe and NOC tooling) with modern cloud engineering, having moved from senior systems programming into cloud product and consulting roles. Based in Lovettsville, Virginia, he has a knack for translating executive priorities into practical, auditable technical plans and tooling. Now retired, he brings a rare combination of operational grit, migration-scale planning, and security automation expertise.
