PROFESSIONAL EXPERIENCE

SENIOR DEVOPS & PLATFORM ENGINEER

Noblis, April 2021 – Present

• Cloud Migration: Led the migration of a legacy monolith and containerized microservices to a multi-AZ AWS architecture (10+ EKS clusters, ~200 nodes, 100+ services), moving 30 TB via Snowball/Snowcone with zero data loss and under 3 hours of downtime.

• Landing Zone & HA/DR: Designed the landing zone on Direct Connect and Transit Gateway with strict subnet isolation and an HA/DR database cluster, achieving 99.95% uptime, <5-minute RPO, and <30-minute RTO.

• Reliability Engineering: Defined SLIs/SLOs in Datadog and the ELK Stack, ran chaos experiments and load tests before major releases, and owned final escalation in the PagerDuty on-call rotation, cutting cross-team triage time by 42%.

• Release & Platform Engineering: Standardized pipelines across Harness, Jenkins, and GitLab CI with canary and blue-green deployments and automated rollback, reducing deployment failures by ~40%. Delivered Backstage golden- path templates and Python/Bash automation that eliminated ~70% of manual toil.

• DevSecOps & Compliance: Hardened AWS accounts and EKS clusters to CIS Benchmarks and NIST 800-53 controls supporting FedRAMP. Centralized secrets in HashiCorp Vault and KMS, and added Snyk, Checkov, tfsec, SBOMs, and image signing to CI, with findings in GuardDuty and Security Hub.

• Event-Driven Re-Architecture: Replaced batch SFTP processing with an EventBridge, SQS, and serverless pipeline, cutting processing time from 3 hours to <2 minutes for 20+ external partners.

• Edge Security: Managed Akamai WAF, rate limiting, and CDN for mission-critical applications, blocking 1M+ malicious requests monthly and reducing false positives by 60% through Splunk-driven tuning. DEVOPS ENGINEER

American Public University System, September 2019 – March 2021

• Observability Re-Platform: Led the migration from Wavefront to Prometheus, Grafana, and OpenTelemetry with SLO-driven alerting, cutting MTTR by 40% and alert noise by 45%; helped establish blameless post-mortem practice.

• Infrastructure as Code: Built a reusable Terraform module library for AWS and Azure (VPC segmentation, IAM boundaries, SCPs, encryption defaults), reducing environment provisioning from days to hours.

• DevSecOps & GitOps: Embedded Trivy and SonarQube scanning into CI, enforced OPA/Gatekeeper admission policies, and standardized GitOps delivery on ArgoCD, Helm, and Kustomize.

• Multi-Cluster Platform: Supported five Kubernetes clusters on AKS, EKS, and VMware TKG (~120 nodes, 60+ microservices) across five regulated jurisdictions; implemented Istio mutual TLS for zero-trust service-to-service traffic.

• Cloud Economics: Led cost optimization with Kubecost, Karpenter, and AWS Auto Scaling, saving ~$150K in annual compute.

CLOUD ENGINEER I

Home Depot, June 2019 – August 2019

• Built and extended Terraform modules and ARM templates to provision microservice environments across AWS and Azure.

• Configured CloudWatch and Azure Monitor alerting with severity tiers and escalation paths, and supported VPC peering, VPN, and firewall configuration for hybrid connectivity. EDUCATION
