Multi-Cloud GitOps Platform

A growing engineering team needed a consistent way to deploy services across AWS and GCP without environment drift or manual provisioning.

Built a GitOps platform using ArgoCD and Terraform that reconciles cluster state from Git, with policy guardrails and automated drift detection.

Git repository as single source of truth → ArgoCD controllers per cluster → Terraform modules for cloud resources → OPA policy gates → Slack notifications.

Eliminated configuration drift across environments and reduced deployment lead time from days to minutes through pull-request-driven infrastructure changes.

• Git as the single source of truth for both infrastructure and application state
• OPA policy gates on every PR before anything reaches a cluster
• Hourly drift detection with Slack alerting
• External Secrets Operator backed by AWS Secrets Manager
