Nikita developed two features for the tailscale/tailscale repository, focusing on enhancing tailnet identity and usability. They introduced an optional Tailnet Display Name field, allowing users to assign intuitive identifiers to tailnets, which streamlined both UI recognition and CLI profile management. By extending the CLI to support profile switching based on these display names, Nikita aligned backend and CLI behavior, reducing confusion during tailnet selection. The work leveraged Go for backend and CLI development, with an emphasis on API design. These changes improved onboarding and operational efficiency, laying a foundation for more robust, display-name-driven workflows across the platform.
