About
At Mineral Resources (Dec 2024 - Present), I led the multi-cloud transformation—migrating from AWS CDK to Terraform to enable operations across AWS and Azure. Built a self-hosted Terraform solution replacing Terraform Cloud, then deployed it across 95 accounts via Azure DevOps Pipelines.
Before that, spent 5 years at Verizon Connect in Dublin (May 2019 - Sep 2024), migrating 200+ repositories to GitLab, moving workloads from EC2 to Fargate, and engineering source-controlled Octopus Deploy templates with complex state synchronization across environments.
Started in Ireland with a First Class Honours BSc in Internet of Things (Jan 2014 - Jun 2019), winning the SunLife 2019 Enterprise Award for an IoT tracking system. Career focus: architecture-first problem-solving and full-stack infrastructure ownership.
