Worked on the polkadot-js/apps repository to enhance production stability by performing a targeted configuration cleanup. Focused on removing deprecated endpoints for Aleph Zero and Integritee-Kusama from key configuration files, the update reduced the risk of misconfiguration and eliminated obsolete connection points. The approach involved careful editing of TypeScript-based production.ts and productionRelayKusama.ts files, ensuring that only active and supported endpoints remained. This change improved code health and streamlined future deployments by making the configuration more maintainable. Leveraged skills in configuration management and frontend development to deliver a precise bug fix, with clear commit traceability for audit and rollback purposes.
