Cloud Platforms & Multi-Cloud Architecture
Expertise designing and operating scalable, resilient multi-cloud platforms across AWS, Azure, GCP, and OCI - hybrid networking, multi-region infrastructure spanning multiple accounts, and fully isolated single-tenant environments.

Infrastructure as Code & Automation
Deep proficiency in Pulumi (Python/Go), Terraform, Terragrunt, and Ansible, with hands-on experience migrating core infrastructure from Terraform to Pulumi for conditional multi-tenant networking - enabling automated single-tenant deployments into independent AWS accounts.

Orchestration & CI/CD Pipelines
Extensive experience building and operating CI/CD pipelines across all environment types, with strong Kubernetes orchestration on EKS, AKS, and GKE, Helm-based deployments, and container immutability standards.

Cloud Networking
Strong background in cloud and hybrid networking - Transit Gateway, OSPF/BGP, IPv6, IPsec, Hybrid VPN. Experience leading enterprise pre-sales and customer architecture engagements: assessing client network topologies, proposing interconnection solutions (Transit Gateway peering, IPsec VPN, private connectivity), and translating complex requirements into implementable designs.

AI & Agentic Engineering
First-mover production experience with agentic SRE tooling on the Claude Agent SDK and AWS Bedrock - architected and shipped the first network observability layer with baseline traffic visibility and anomaly detection across EKS and AWS, eliminating ~$2k/month in NAT Gateway costs. Positioned to advise on agentic observability architecture and LLM-driven SRE tooling adoption in production AWS environments.

Compliance & Security
Track record in GxP/CAPA-regulated environments, SOC 2, compliance-as-code, and audit-ready infrastructure - led DevOps teams through 2-3 GxP infrastructure audits contributing to successful ISO certification.

Site Reliability Engineering (SRE) Staff-level SRE practice across multi-region SaaS production: SLO/SLI definition, error budget management, incident response and post-mortem culture, on-call rotation design, and observability across metrics, logs, and traces. Hands-on operation of EKS, AWS networking, and IaC at enterprise scale, combined with technical leadership of SRE teams - setting reliability direction, mentoring engineers, and running Scrum ceremonies.

Performance Engineering
CDN and infrastructure routing optimisation, delivering significant latency improvements - including an 80% reduction in feature flag evaluation latency for EU customers (500ms to under 100ms).

Systems & Network Engineering
Early-career foundation in SDN, OpenStack-based IaaS, OSPFv6/BGPv6 routing on national distribution networks, and HA load balancing with NGINX and CloudFlare - R&D under EU FP7/Horizon 2020 programmes.

Introduced an ITIL-based change management process for infrastructure.

DevOps Engineer

AstraZeneca (Definiens)
Engineered hybrid storage for 5PB of GxP-regulated medical imaging data using Quobyte and AWS Storage Gateway. Deployed and automated on-premise Kubernetes clusters using Ansible. Acted as primary engineer for the initial lift-and-shift of legacy workloads to AWS. Audited and reverse-engineered legacy network architectures to establish secure interconnections between local offices, AstraZeneca's global network, and AWS.

Senior Systems Engineer

Evoke Gaming Ltd
