- Developed and operated a Kubernetes-based platform for containerized applications, working as part of a scrum team in an agile dev/ops environment.- Designed and implemented containerized services with REST APIs to manage infrastructure, install and upgrade clusters, provide persistent storage, and manage several layers of security. - Specialized in automatically managing infrastructure such as servers, networks, subnets, security lists, load balancers, custom images, and storage volumes in both OpenStack and OCI (Oracle's equivalent to AWS)- Created modular Terraform configuration for managing thousands of security list rules across dozens of interconnecting subnets- As a master of several key projects in GitLab, I reviewed all the code going into those projects, ensured the CI/CD pipelines successfully deployed the changes into staging, dev, and production environments, and was the primary contact for support issues.- Solved difficult problems such as continually repaving nodes in the clusters to keep them up to date and regularly rotating certificates to ensure security.- Developed build processes to build 3rdParty applications as Docker containers, including Glusterfs, Jenkins, Calico/Flannel, and various Kubernetes services.- Provided tier 3 support to multiple 24/7 production environments and demonstrated team-leading troubleshooting skills to resolve incidents quickly. Also rotated in as a single point of contact for the group, responsible for making sure all support issues are handled promptly.

- Built and maintained a linux based operating system that served as a platform and virtualization host for high availability telecom applications- Developed and tested tools to check system health and raise alerts, modify system settings (such as networking, iptables, and ntp), provide an easy-to-use interface to KVM virtualization, and upgrade/rollback servers.- Lead the development of an automation framework using Electric Commander that ran dozens of upgrade paths in parallel as well as suites of unit tests on various releases and hardware types.- Built various linux packages from source with custom patches to address bug fixes before they were fixed upstream, including in the kernel

Developed automated and manual tests for satellite communications equipment such as handsets and routers.
