DevOps engineer with 6+ years on cloud automation and fintech infrastructure. I run multi-account AWS estates and keep production microservices healthy on Kubernetes and ECS. Most of that work sits under PCI-DSS audit, so I spend real time on supply-chain security. The rest goes to open-source developer tools.
