Modernised a legacy monolith into containerised microservices orchestrated by Amazon EKS. Helm charts drive repeatable deployments, Argo CD enforces GitOps practices, and automated integration tests validate each change before progressive delivery reaches production.

• Implemented blue/green rollouts with Argo Rollouts to safeguard weekly releases.
• Enabled horizontal pod autoscaling that adapts to peak sporting-event traffic.
• Streamlined day-2 operations via Grafana dashboards and Kubernetes event logging.

Designed an observability stack that ingests, stores, and visualises low-latency match data for real-time decision making. Unified metrics, logs, and traces empower engineers and analysts to diagnose incidents in minutes.

• Deployed Prometheus Operator with Helmfile to manage more than 150 scrape configs.
• Integrated Loki and Tempo for correlated log and trace analysis within Grafana.
• Crafted alerting pipelines with Alertmanager and PagerDuty to reduce noise.

Codified the company's AWS foundation with reusable Terraform modules. Automated account vending, networking, and guardrails so product teams can launch environments in minutes while staying compliant.

• Provisioned core networking with Transit Gateway and cross-account Route 53 Resolver.
• Implemented policy-as-code checks (tfsec, Checkov) inside GitHub Actions workflows.
• Delivered self-service environment catalogues via Terraform Cloud and Service Catalog.

Built reusable GitOps patterns that govern dozens of services. ApplicationSets template tenant environments, GitHub Actions enforce policy checks, and Cosign signs container images before promotion.

• Introduced automated drift detection and chat-ops approvals for production changes.
• Packaged CI checks into composite actions to standardise testing and security scanning.
• Documented runbooks and architecture diagrams to accelerate onboarding.
