Kaluza
2025 – PresentPrincipal Platform Engineer (Contract)
Engaged through Burtenshaw Technology. Working at principal scope on a unified AWS platform. EKS, Terraform, ArgoCD, Kafka, observability with Datadog. Hands-on across the full stack.
Burtenshaw Technology Limited
Principal DevSecOps & Platform Engineer.
I design, build, and secure the cloud platforms product teams ship on. Ten years across full-stack engineering, architecture, and security. Still hands-on, still writing code most days.
Internal platforms that give product teams safe autonomy. Paved roads, not fences.
Consolidating fragmented multi-cloud estates into unified, governed AWS architectures.
Security baked into the pipeline as defaults. Scanning, policy-as-code, signed artefacts.
Cloud posture and configuration review. Threat models with remediation that lands.
I operate at principal but still write code, build infra, and review pull requests. Distance from implementation makes for worse architecture.
Long full-stack background in TypeScript and React. I design platforms with a deep understanding of how applications are actually built and shipped.
Scanning, infra policies, and compliance baked in from the start. I build guardrails teams move fast inside, not fences they route around.
