PROFILE
Martin Cayuelas
Martin Cayuelas contributed to the LedgerHQ/ledger-live repository by architecting and delivering modular UI systems, scalable navigation, and robust state management for cross-platform wallet features. He migrated core data layers to RTK Query, refactored the desktop Market to MVVM architecture, and introduced virtualization with @tanstack/react-virtual to improve performance. Using TypeScript, React, and Redux, Martin enhanced developer tooling, implemented feature flag-driven rollouts, and strengthened end-to-end testing with MSW and Playwright. His work included deep refactoring, codebase cleanup, and UI/UX modernization, resulting in more maintainable, testable, and reliable product flows that accelerated feature delivery and improved user experience.

Jul 1, 2025July 2025 focused on stabilizing user flows, expanding ModularDrawer architecture, and improving scanning/QR robustness. Delivered major architectural work for ModularDrawer (core architecture, registry pattern, Redux state, and integration with existing components) and a comprehensive test suite, enabling safer, scalable UI modules. Advanced MAD integration (asset and network selection, and AddAccount flow). Implemented key AddAccount enhancements (Title step dynamics, entry points for MAD, and test coverage). Improved scanning and QR reliability (banner interaction fix, crash fix for LLm scanning, ledger sync QR display fix, and legacy QR import/address scan robustness). Targeted cleanup (remove deprecated AddAccountV1 flow, remove dead code, and refactor utilities) to reduce maintenance cost. Result: faster feature delivery, reduced bug risk, and a more maintainable, cross-platform codebase.
