Worked on backend reliability and data correctness improvements for the superfly/flyctl repository, focusing on cluster management. Addressed a bug where cluster version information for mpgv2 was not accurately reflecting the cluster type, ensuring users now see correct version data. Refactored the handling of region information by removing the Region field from CreateClusterParams and instead fetching region details from the server response, which improved accuracy and reduced user confusion. Removed an unused ClusterId field to streamline the data model. Demonstrated skills in Go, API integration, and backend development, with a focus on clean refactoring and version-aware server-side logic.
