Our core goals are to maintain systems up-to-date, secure and reliable. We host a variety of solutions but main stack is Kubernetes for computational resource orchestration and ArgoCD and ArgoWorkflow for CI/CD implementation. Got experienced in dealing with Helm charts, Kubernetes in GCP and GitOps operations and automation of CI through workflow generation. Also did improvements in the architecture of our o11y proposal and helped tweak the knobs of cost versus engineering time balance when building this ecosystem.Process maturity, community engagement and tech evangelism are among my day-to-day activities, aiming to make SRE a beacon of good engineering practices throughout our company.
