Cloud Architecture

Staff Operations Engineer | SRE DevOps Tech Lead
Staff Operations Engineer | SRE DevOps Tech Lead
  • Team Leadership: Served as Tech Lead for the Feature Flags SRE team - set technical direction and infrastructure roadmap, ran Scrum ceremonies, and guided 3 engineers across reliability, observability, and deployment workflows.
  • Cloud Architecture: Designed and operated a multi-region AWS infrastructure (US-East, US-West) for the CloudBees DevSecOps SaaS platform, spanning 20+ AWS accounts across shared SaaS and fully isolated single-tenant environments.
  • Next-Gen SRE: Built the organisation's first network observability layer using the Claude Agent SDK and AWS Bedrock - establishing baseline traffic visibility and anomaly detection across EKS and AWS where none existed before. Traffic analysis identified routing inefficiencies that, by shifting to internal VPC endpoints, eliminated ~$2k/month in NAT Gateway processing costs in production alone.
  • Performance Engineering: Optimised CDN configuration for the Feature Flags product, reducing flag evaluation latency for EU customers from ~500ms to under 100ms - an 80% improvement without infrastructure changes.
  • Modern Deployments: Built and operated CI/CD pipelines spanning every environment type - SaaS production, pre-prod, QA, test, and customer demo environments, plus fully isolated single-tenant AWS accounts. Extended the same pipeline framework to automate customer network interconnections: Transit Gateway peering, IPsec VPN provisioning, and per-tenant NACL rule application - eliminating manual steps from enterprise customer onboarding.
  • IaC Migration: Migrated core infrastructure from Terraform to Pulumi (Python/Go) when HCL ran out of expressiveness for conditional multi-tenant networking - automating isolated single-tenant deployments into independent AWS accounts, with dynamic CIDR validation and real unit and integration tests.
  • Customer Architecture: Represented CloudBees in enterprise sales and pre-sales engagements-assessed customer network topologies, proposed and explained interconnection architectures (Transit Gateway, IPsec VPN, private connectivity), and translated complex infrastructure requirements into implementable solutions.

Delivered the cloud version of the radiology reporting platform on AWS

Senior DevOps Engineer
Senior DevOps Engineer
  • Team Leadership: Led a team of 3 DevOps and 2 IT engineers, establishing Agile/Scrum ceremonies that increased deployment transparency and team velocity.
  • Platform Delivery: Delivered the cloud version of the radiology reporting platform on AWS - introducing IaC-controlled, structured cloud infrastructure for a 50-developer engineering org that previously had no standardised provisioning. Maintained parallel on-premise containerised installations. Unified identity management across Azure Active Directory and AWS.
  • Kubernetes & EKS Migration: Introduced EKS and container immutability standards - replaced a workflow where developers SSHed into long-lived containers and edited files directly with proper image-based, immutable deployments.
  • Release Engineering: Built the complete release infrastructure from scratch - GitLab CI pipelines across QA, pre-prod, and production, Terraform-managed AWS environments, and Packer-based image builds for on-premise deployments - where no structured release process existed before.

Senior DevOps Engineer
  • Engineering Leadership: Directed internal engineers and external contractors across the full infrastructure lifecycle; led technical hiring for the DevOps team and mentored junior engineers.
  • Cloud Migration Strategy: Spearheaded the migration of 200+ VMs from on-premise to AWS; architected and automated the hybrid-cloud environment using Terraform and Ansible.
  • GxP Architectural Lead: Led the design and implementation of infrastructure architectures that met strict GxP requirements; functioned as the technical lead for infrastructure audits.
  • CAPA & Audit Leadership: Led the DevOps team through 2-3 GxP infrastructure audits contributing to successful ISO certification - operationalised Corrective and Preventive Actions (CAPA) within the DevOps process, ensuring automated guardrails and technical controls met regulatory requirements.
  • Change Management: Introduced an ITIL-based change management process for infrastructure-establishing structured approval workflows, change request procedures, and rollback standards that aligned DevOps practices with GxP regulatory requirements.

  • Petabyte-Scale Storage: Engineered hybrid storage for 5PB of GxP-regulated medical imaging data, accessible across EU and US sites, using Quobyte and AWS Storage Gateway under strict throughput and compliance requirements.
  • Infrastructure Automation: Deployed and automated on-premise Kubernetes clusters using Ansible; managed high-availability VMware/Hyper-V virtualisation layers.
  • Cloud Migration Execution: Acted as the primary engineer for the initial lift-and-shift of legacy workloads to AWS, implementing the first automated CI/CD pipelines and Terraform modules.
  • Network Reverse Engineering: Audited and reverse-engineered legacy network architectures to establish seamless, secure interconnections between local offices, AstraZeneca's global network, and AWS.

SUMMARY

With 15+ years in DevOps, SRE, and a strong networking background, I architect and run scalable, resilient multi-cloud (AWS, Azure, GCP, OCI) platforms - from hybrid networking and CI/CD pipelines to Helm-based EKS deployments and Agentic Workflows. At CloudBees, I owned the multi-region AWS infrastructure spanning 20+ accounts, drove the IaC migration from Terraform to Pulumi (Python/Go) to handle conditional multi-tenant networking at scale, and built the organisation's first network observability layer using the Claude Agent SDK. Previously led DevOps and infrastructure at AstraZeneca (GxP/CAPA, 5PB medical imaging across EU and US) and Smart Reporting (MedTech, 50-developer engineering org). Open to Staff SRE, Head of Infrastructure, and Architect engagements - full-time, contract, or fractional.
