Production Kubernetes for financial services.
Delivering Kubernetes-based infrastructure for banking-grade production environments across Azure and AWS.
Selected work
AWS → Azure: Multi-cloud migration at scale
Managed Hosting platform · 10+ banking clients · GitOps modernisation
Backbase needed to migrate 10+ production banking client environments from AWS EKS and private Azure tenants into a unified Managed Hosting 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.
Datadog → Grafana: Observability platform migration
Multi-tenant · Prometheus + Loki · Centralised alerting & audit logging
tenant
The existing Datadog-based observability stack was costly and inflexible at multi-tenant scale. Dashboards were slow due to high metric cardinality, and incident notification was fragmented across teams and customers with no unified standard.
Contributed to the strategic migration from Datadog to a Grafana + Prometheus + Loki stack. Implemented adaptive metrics and datasource caching to reduce cardinality and improve query speed. Built a multi-channel alerting framework integrating PagerDuty, Slack, Microsoft Teams, and email. Centralised audit log archiving across Kubernetes, SQL, app services, and Azure Front Door — with secure third-party access via Key Vault-managed SAS tokens.
Caching platform & Kubernetes governance at scale
Azure Managed Redis · Active-active geo-replication · Kyverno policy framework
Backbase's Managed Hosting required a production-grade, multi-tenant caching layer with no downtime tolerance, alongside consistent security governance across Kubernetes clusters at enterprise scale.
Architected and delivered a multi-tenant caching platform on Azure Managed Redis, introducing an active-active geo-replication model with a validated zero-downtime cutover strategy. In parallel, standardised Kyverno policy frameworks across clusters, strengthening governance and security compliance across the entire Managed Hosting platform.

About
I'm a Senior Platform Engineer specialising in Kubernetes infrastructure, cloud migrations, and observability platforms. I've spent the last four years at Backbase building and scaling the infrastructure that powers banking software for clients across Europe.
My work sits at the intersection of reliability and developer experience — designing systems that are secure and operable by default, not as an afterthought. I hold six certifications across Kubernetes, Azure, AWS, and Terraform, and I care deeply about platform governance and operational clarity.
I'm open to senior platform, SRE, and cloud architecture roles or consulting engagements — particularly in fintech, regulated industries, or organisations operating Kubernetes at scale.
