Production Engineering Portfolio

Senior Cloud DevOps Engineer

Senior Cloud DevOps Engineer with 9+ years across software engineering and cloud engineering, including nearly 6 years operating production cloud infrastructure. I lead a five-engineer DevOps team supporting 12 AWS accounts across two regions and multiple EKS environments, with measurable outcomes including approximately 70% less manual provisioning, incident investigation reduced from several hours to under 45 minutes, roughly 20% lower AWS spend, near-zero-downtime database migrations, and protection of 99.9% availability targets.

Selected engineering decisions

How I make infrastructure decisions

Review implementation evidence →

DELIVERY AUTHORITY Git defines desired state

Promotion, rollback and drift remain reviewable through versioned GitOps changes rather than manual cluster state.

Internal Developer Platform → WORKLOAD SAFETY Guardrails before scale

Non-root workloads, probes, quotas, NetworkPolicy, autoscaling and environment separation are designed into the runtime.

Kubernetes Platform → RECOVERABILITY RTO/RPO drive topology

Recovery architecture begins with business objectives, explicit failover ownership, rollback criteria and evidence.

Multi-Region DR → PLATFORM BOUNDARY Governance is part of delivery

Identity, network, secrets, observability and cost controls are versioned with the landing-zone foundation.
