Case Study: Data Quality Solutions Company achieves rebrand-ready design system modernization with EffectiveSoft

Data Quality Solutions Company modernizes its React SaaS platform with EffectiveSoft using 140+ design tokens

The customer, a data quality solutions company, faced a significant challenge when planning a rebrand of its B2B SaaS platform. Its React-based front end had grown into a brownfield codebase with visual rules hardcoded across hundreds of components and SCSS files, making consistent updates impossible. EffectiveSoft was engaged to modernize the design system and create a rebrand-ready UI.

EffectiveSoft implemented an incremental modernization strategy, avoiding a full rewrite. Using Claude Code for AI-assisted refactoring, they established a design contract with 140+ tokens and migrated 550+ files. The solution included CI enforcement and automated visual regression testing. Results included eliminating MUI leakage, consolidating legacy components, and creating a governed design layer. This drastically reduced the cost of future changes and made the platform ready for a rebrand through simple token updates.
