Backbase's Managed Hosting required a production-grade caching layer alongside consistent security governance across Kubernetes clusters at enterprise scale.

Architected and delivered a multi-tenant caching platform on Azure Managed Redis, migrating from Azure Cache for Redis with a redesigned active-active geo-replication model and validated zero-downtime cutover. Standardised Kyverno policy frameworks across clusters, strengthening platform governance and security compliance.

The Grafana stack offered better cost efficiency and flexibility at scale. Dashboards needed optimisation due to high metric cardinality, and incident notification was fragmented across teams and customers with no unified standard.

Reduced metric cardinality with adaptive metrics and datasource caching. Built multi-channel alerting (PagerDuty, Slack, Teams, email) and centralised audit log archiving across all platform services with secure third-party access.

Backbase made a strategic decision to consolidate production environments from AWS EKS and private Azure tenants into a unified platform on AKS — with no tolerance for downtime across regulated financial services workloads.

Led end-to-end environment migrations, standardised GitOps workflows by migrating from FluxCD to ArgoCD with Helm, and moved 50+ repositories and CI/CD pipelines from Azure DevOps to GitHub Enterprise, adopting GitHub Actions across the board. Mentored junior engineers throughout.
