22 days, 94% cost reduction with AI
Enterprise UI Migration
Led an AI-assisted migration of a large-scale enterprise component library from custom React components to shadcn/ui across 16 applications and 28 shared libraries. Achieved 7x faster execution and 94% cost reduction compared to traditional approaches.
The Challenge
The organization faced significant technical debt with 200+ hours of annual maintenance on custom UI components. The migration scope included 715 TSX files, 705 Storybook stories, 485 unit tests, and 99 E2E tests—a scale that would traditionally require months of work from a full team.
The Solution
Implemented an AI-assisted methodology using Claude Code for 90% of the work: analyzing existing components, generating shadcn/ui equivalents, updating consumer files, and migrating tests. Human oversight (10%) focused on PR reviews, architecture decisions, POC validation at critical checkpoints, and accessibility compliance. An 8-wave timeline with built-in risk mitigation and fallback strategies ensured quality without sacrificing speed.
