Drive production incident response and deep-dive root-cause analysis across Windows Server, cloud, and container platforms. * Engineer secure cloud infrastructure. Design, implement, and maintain secure, scalable cloud architectures across Windows and Linux systems; work independently or lead small teams. * Automate with IaC (secondary).
