Andrew Greig Barr refactored the Web Agent UI architecture and routing for the EmberAGI/arbitrum-vibekit repository, focusing on modularizing components and streamlining navigation for agent management and hiring workflows. Using Next.js, React, and TypeScript, he restructured the base code to improve maintainability and reduce future technical debt. His work clarified UI component boundaries and routing paths, which supports faster onboarding for new contributors and facilitates cross-team collaboration. By enhancing the organization of the codebase and introducing a more intuitive routing system, Andrew laid a foundation for accelerated feature delivery and easier testability in the Web Agent UI moving forward.
