Site Reliability Engineer at Sephora EMEA, migrating Windows workloads to GCP with GitOps.

Canada
Message

At Sephora EMEA, I designed a GitOps model to migrate on-premise Windows application servers to GCP Compute Engine. With Config Connector, Kustomize, and ArgoCD, a new VM can be onboarded using templated YAML without console access.

I also standardized VM security with Identity-Aware Proxy, automatic Active Directory joins, and OPA Gatekeeper policies. For Kubernetes, I deployed n8n on GKE with Cloud SQL and Memorystore, using Workload Identity and IAM database authentication.

At Deloitte, I built production pipelines for AWS account creation, Terraform provisioning, and Kubernetes and OpenShift deployments. I also implemented identity and access workflows and led an AI-based tool evaluation that reduced software selection time by 60%.

Earlier, at Neoxia, I managed AWS and GCP cloud operations, implemented monitoring and GitOps practices, and conducted incident post-mortems. My experience also includes leading QA for telecom platforms at HeadMind Partners and migrating banking applications from WebLogic to Tomcat at CGI.
