10+ years of experience building, testing, and maintaining infrastructure and apps — designing architectures with security best practices in mind. I have hands-on experience with AWS, Azure, Kubernetes, Terraform, and CI/CD pipelines, with Golang for automation. I've applied these skills to automate and deliver mobile and web apps, backends, and infrastructure for companies around the world.
