Profile
Cloud and platform engineer with 6 years running production infrastructure on AWS and Azure, most of it in regulated healthcare. I build internal platforms with Terraform, Kubernetes and GitOps, put security gates into CI/CD, and run SRE practice: SLOs, observability, on-call and postmortems. Cut AWS costs by 63% at Moorfields Private Eye Hospital while keeping patient-facing systems at 99.95% uptime. Current focus is AI infrastructure: integrating LLM services (Amazon Bedrock, OpenAI, Azure AI) with cost controls and least-privilege guardrails.

Professional Experience
Founder & Cloud / AI Infrastructure Consultant
Feb 2026 – Present
HumanLayer AI Ltd, London
- Independent consultancy delivering AWS cost and reliability reviews, AI spend and guardrails reviews, and implementation sprints for UK engineering teams.
- Open-sourced an AWS FinOps tool (Python, Terraform) that turns waste into an approval plan: gp2-to-gp3 migration with IOPS parity, safe snapshot clean-up, Compute Optimizer rightsizing, and read-only versus least-privilege apply roles.
- Open-sourced an LLM guardrails gateway (Python): per-team budgets enforced before each model call, cost per call, redaction of personal data, tool allow-lists, human approval for risky agent actions and a tamper-evident audit log.
Site Reliability Engineer & Cloud AI Integration Specialist
Aug 2022 – Present
Luul Solutions Ltd, London
- Implemented an SLA/SLO/SLI framework with automated monitoring across 15+ services.
- Built a golden-image pipeline (Packer, Trivy, Amazon Inspector) and a Terraform-provisioned Jenkins platform on AWS with a disposable, EFS-backed controller and security-gated infrastructure pipelines (tfsec, Checkov, Gitleaks, approval before production).
- Delivered GitOps on Azure AKS: layered Terraform, build-once images promoted by Git commit, ArgoCD, Key Vault secrets via CSI, and a Trivy image gate with SBOMs.
- Ran production Kubernetes (EKS, AKS, GKE) and CI/CD with GitHub Actions and AWS CodePipeline; maintained reusable Terraform modules for AWS, Azure and GCP.
- Built AI integrations with guardrails: Amazon Bedrock drafting IAM policies within permission boundaries, and serverless services orchestrating Azure AI Speech, OpenAI and Google Vision.
- Built monitoring, logging and alerting (Prometheus, Grafana, CloudWatch, ELK) with on-call rotation, runbooks and postmortems.
