Worked on the pulumi/pulumi-junipermist repository to enhance upgrade reliability by refining how upgrade IDs are managed for upgrade-related resources. Addressed a bug in the applyResourceIDs function by ensuring that the upgrade_id is only applied to resources whose Terraform token begins with 'mist_upgrade', thereby reducing deployment risks and preventing misapplication of upgrade identifiers. This targeted fix improved deployment safety and resource handling within the provider. The work was implemented using Go and focused on Terraform provider development, demonstrating attention to detail in resource management and a methodical approach to maintaining robust infrastructure-as-code workflows within the Pulumi ecosystem.
