June 2025 performance summary for Layer-Fi/layer-react: Delivered data-loading for customers and vendors, introduced improved selection components, and enhanced UI/UX across core flows. Implemented a SecondPartySelector/CustomerVendorSelector (using react-select) for cleaner customer/vendor workflows, plus TagSelector UI improvements and modal UX enhancements. Added ledger tag interaction hooks and mock data enhancements. Progressed release readiness with multiple version bumps (alpha.3 through alpha.6) and tooling upgrades. Major bugs fixed included correcting the default npm publish tag to prevent unintended alpha releases, reducing re-renders by cleaning up useEffect usage, color saturation adjustments, and several UI fixes (bank-transaction animations, trailing spaces in folder names, and revalidateOnMount behavior). Overall impact includes faster data onboarding, more reliable and scalable UI for business workflows, and a cleaner, more maintainable codebase. Technologies/skills demonstrated include React hooks and patterns, react-select integration, data-loading techniques, CSS variable modernization, linting/tooling upgrades, and structured release management.
