What I'm looking for

I'm looking to build and improve secure, resilient cloud platforms, lead production incident remediation, automate infrastructure, and reduce cloud costs.

I'm a platform and reliability engineer with six years of experience across AWS, Azure, Kubernetes, infrastructure security, incident remediation, and cloud cost management.

At me&u, I'm leading remediation of a high-severity feature flag outage across 22 services, modernising credentials with managed identities and Workload Identity Federation, and hardening privileged authentication through Auth0 TOTP and step-up reauthentication.

Previously at Coles, Tyro Health, Shine Solutions, and Lexer, I built Kubernetes and AWS infrastructure, automated operations with Python and Bash, delivered Terraform and CloudFormation infrastructure, improved CI/CD, and supported production systems.
