About me
Who I am
I've spent more than ten years designing and operating dependable cloud estates across UK public sector and FCA-style environments—with a constant focus on change control, audits, and risk-aware automation that still ships outcomes for delivery teams.
My day job is infrastructure as code, multi-account AWS governance, and CI/CD that teams can trust: secure-by-default patterns, measurable guardrails, and observability that helps you fix issues before customers notice.

Highlighted outcomes
Multi-account AWS automation & landing zones
Automated AWS organisations with SCPs, permission boundaries, and Account Factory / PALZ-style controls—pairing auditable CodePipeline flows with secure account provisioning.
200+ repository migration with quality gates
Migrated a large GitHub estate for identity teams and wired SonarQube into CI for automated security and quality checks—keeping squads shipping while standards improved.
Blue/green patterns & DR-ready foundations
Introduced repeatable blue/green release paths on AWS workloads and built DR/BCP thinking into Terraform-managed estates for Windows and Linux platforms.
Centralised observability across accounts
At enterprise scale: Route 53, CloudFront, WAF protections, plus consolidated logging routed to SOC visibility—paired with infra modules teams could reuse.
