Kubernetes clusters operated on Citi's centralised, multi-tenant GKE platform.

I build the cloud, Kubernetes and delivery foundations teams rely on.
I treat infrastructure like a product, with real users, a roadmap and outcomes you can measure. 10+ years across platform engineering, DevOps and SRE, most recently building GKE platforms for Citi and delivery platforms for Lloyds Banking Group.
Platform outcomes you can scan in seconds.
Teams self-serving Lloyds' GCP Internal Developer Platform, with environment provisioning 70% faster.
Engineering hours saved annually through automation, earning 2× Champion of the Year at RealPage.
Years across platform engineering & SRE on AWS, Azure and GCP.
Infrastructure built like a product.
With real users, a roadmap, paved paths and outcomes you can measure.
That shift from infrastructure admin to platform product thinking is what I bring to every team. I design reusable Terraform modules across AWS, GCP and Azure that teams self-serve without opening a ticket, build GitOps delivery with Argo CD and Harness that removes manual gates and stand up observability stacks (Prometheus, Grafana, Loki) that give SRE teams signal, not alert noise.
I have spent the last few years in regulated financial-services environments, implementing Kubernetes security postures (Workload Identity, Pod Security Standards, OPA Gatekeeper) that pass bank-grade audits. I am now focused on platform, SRE and AI/MLOps platform work at product scale.
Languages spoken
The layer between product teams and raw infrastructure.
Not pure application development, not pure ML research. The platform, automation and operational foundations that let application, analytics and ML teams deliver reliably.
Cloud platform enablement
Self-service Terraform modules, IAM patterns, networking baselines and deployment standards across AWS, GCP and Azure, so teams consume platforms without filing tickets.
GitOps delivery & reliability
Argo CD and Harness pipelines that replace manual kubectl, cut deployment incidents and pair with Prometheus / Grafana / Loki observability for fast P1 resolution.
Secure platforms for data & ML
Kubernetes security at audit grade (Workload Identity, Pod Security Standards, OPA Gatekeeper) plus model-serving and automation foundations for AI / MLOps teams.
Recent roles and regulated platform work.

Jul 2022 – Present · London, UKClients: Citi & Lloyds Banking Group
Citi · GKE Public Cloud Platform · Jan 2025 – Present
- Operate Citi's centralised GKE platform as a multi-tenant shared service for hundreds of clusters bank-wide, with namespace isolation, platform controls and Tier-1 regulatory compliance.
- Built reusable Terraform Enterprise modules for cluster provisioning with Sentinel policy enforcement that blocks security misconfiguration across the estate.
- Manage fleet-wide configuration with Argo CD and Helm, with drift auto-remediated. Define cluster-tier SLOs and lead incident response and blameless postmortems.
Lloyds Banking Group · GCP Platform & Data Analytics · Jul 2022 – Nov 2024
- Operated Lloyds' GCP Internal Developer Platform, self-service infrastructure for 50+ teams, cutting environment provisioning time 70%.
- Built the GCP data-analytics foundation (BigQuery, Pub/Sub, Dataflow, Composer, Cloud SQL) and enabled Vertex AI & Looker onboarding with IAM and VPC Service Controls.
- Led the Spinnaker → Harness migration standardising GitOps division-wide. Hardened the image supply chain with Aqua + Harbor, raising image-scan compliance 60% and cutting spend 20% through rightsizing.
