Mar 1, 2026March 2026: Delivered a scalable DX foundation for Ledger Live by establishing an NX-based workspace with domain/shared manifests, base descriptions, and robust file/structure rules. Implemented a shared feature-flag package and refactored feature flag state to support remote flags and safer rollouts. Introduced Copilot rules for domain/shared areas to strengthen automation, improved observability with build-time logging and removal of the repack logger, and cleaned tooling. Addressed critical quality issues (referenced file path, API rules, glob patterns) and expanded testing coverage with data-utils tests. Enhanced documentation and typing across core areas to improve developer guidance and consistency.

Apr 1, 2025In April 2025, Ledger Live delivered two high-impact features and completed a mobile storage migration, boosting user experience and reliability. Key features delivered: Graph Pointer Positioning Enhancement, refactoring the graph component to support xOffset and yOffset for precise pointer positioning, improving accuracy and visualization; Storage Migration to MMKV and Migration Tooling, migrating local storage from AsyncStorage to MMKV across Ledger Live Mobile, with wrappers, migration scripts, a debug UI for migration/rollback/reset, and feature-flag controls. Major bugs fixed: improved cartesian coordinate calculation for the graph pointer to ensure pointer accuracy (#9767). Overall impact: enhanced data visualization fidelity, faster and safer storage readiness for mobile experiences, and more controllable rollout via feature flags and debug tooling. Technologies/skills demonstrated: React Native component refactoring, MMKV integration, migration tooling and scripting, feature toggles, debug UI development, linting and changeset discipline, and cross-team collaboration on migration tooling.
