Gustidia worked on the eksctl-io/eksctl repository, focusing on expanding AWS regional support and enhancing cluster observability. She implemented support for the MX-Central-1 AWS region by introducing the necessary region constant and EKS resource account ID, updating the SupportedRegions logic to enable seamless deployments in the new region. Additionally, she integrated metrics-server as the default addon for EKS clusters, ensuring it is provisioned before node groups to provide immediate operational insight. Her work leveraged Go, Kubernetes, and AWS infrastructure, addressing business needs for broader regional coverage and improved monitoring, with a clear focus on maintainability and deployment efficiency.
