DevOps engineer, 6+ years building high-scale cloud automation and fintech infrastructure. I govern multi-account AWS environments, run production microservices on Kubernetes and ECS, and treat everything as code, with a working focus on PCI-DSS compliance and supply-chain security. Alongside client work I build and maintain open-source developer tools.
