Developed and delivered the Client Copy Across Inbound Configurations feature for the mhsanaei/3x-ui repository, enabling administrators to efficiently copy clients between different inbound configurations. This work involved both backend and frontend development using Go and Vue.js, with a focus on streamlining onboarding and reducing manual configuration errors. The implementation included resolving issues with the Copy Clients modal to ensure a reliable user experience and adding comprehensive internationalization support for the new functionality. Deployment processes were stabilized by reverting recent install and deploy script changes, minimizing risk and ensuring safer releases while supporting cross-functional collaboration throughout the development cycle.
