  • Led migration of regulated workloads from on-prem to cloud, redesigning architecture around isolation, security boundaries, and future growth.
  • Introduced controlled failure testing to expose weak points earlier and cut downtime by 20%.
  • Owned end-to-end delivery systems (infrastructure + CI/CD), reducing deployment time by 40% and errors by 35%.
  • Defined Kubernetes RBAC and network segmentation so multiple teams could share platforms without broad access by default.
  • Led incident response, root cause analysis, and reliability improvements across production systems.
  • Tested AI-assisted DevOps automation with guardrails for sensitive data and reviewability.
