Juan contributed to the coopcycle-app and coopcycle-web repositories, focusing on dispatch workflows, task management, and real-time data handling. He engineered centralized Redux state for delivery and task data, migrated APIs to Redux Toolkit Query, and modernized React Native components with hooks and TypeScript. Juan introduced map-based dispatch views, robust search and filtering, and improved UI/UX for task assignment, addressing stale data and navigation issues. He enhanced backend integration and access control, implemented end-to-end and unit testing with Cypress and Detox, and reduced technical debt through targeted refactoring. His work improved data integrity, operational visibility, and maintainability across both platforms.

June 2025: Delivered across CoopCycle web and mobile apps to strengthen dispatch capabilities, enrich task data, and modernize the operator UX. Key data improvements, a map-based dispatch view, and robust search/filters created clearer visibility and faster decision cycles. Refined tooling and tests to ensure data correctness and stability as new features landed.

February 2025 performance summary for coopcycle-app and coopcycle-web. Focused on stabilizing delivery workflows, improving data loading, and expanding test coverage to drive reliability and faster time-to-delivery. Key business outcomes include reduced data coupling, faster UI readiness in Dispatch and Delivery flows, and stronger governance of access controls for dispatcher roles. Key features delivered (business value and technical detail): - Dispatch section UI and data loading: Load stores into Redux when entering the Dispatch area; moved StoreListInput to dispatch/components; render store selector. Commits: be2c26ec, da0beee4, 9b4d02f7. - Delivery module data migration: Moved time slots, timeSlotChoices, and packages from Store reducer to Delivery reducer to centralize delivery-related state and simplify data handling. Commits: 483c0d39, 25f4deb2, 830af7c1. - Backend data capability: Get max stores from backend (100) to support capacity planning and UI hints. Commit: b7963fd4. - App-wide delivery flow access and store fetching improvements: Implemented app-wide delivery flow access (#1950), and fetch all stores on entering NewDeliveryStore to improve UX and reduce loading delays. Commits: ed6d8e7c, f95f9458. - Testability and quality: Added test IDs; added tests for creating deliveries; configured Android-only test runs; addressed test warnings to improve CI reliability. Commits: 2ce81b97, 7b05a8ed, a4180ba5, 7b6adaa4. Major bugs fixed (stability and quality improvements): - Import fixes across modules to eliminate cross-cutting issues. Commits: 4b912cc3, 8d1f4cc8. - Delivery addresses loading fix to ensure accurate delivery data surfaces in UI. Commit: 45dfa16e. - Refresh behavior fix to prevent stale state; improved state reset on logout for security and consistency. Commits: d82b1ac9, 4e1ed2a9. - Delivery price calculation bug fix (NewDeliveryPrice). Commit: 1912d1d2. - Merge conflicts resolution and related cleanup to keep history clean. Commit: 10f98909. Overall impact and accomplishments: - Improved stability and predictability of delivery flows by centralizing delivery-related state and reducing cross-reducer dependencies. - Faster, more reliable UI interactions in Dispatch and NewDelivery flows due to prefetching stores and standardized data fetching. - Expanded test coverage and CI reliability (IDs-enabled tests, Android-focused runs, and new delivery tests), supporting safer deployments. - Strengthened security and UX consistency with state reset on logout and access-control adjustments for dispatcher roles. Technologies and skills demonstrated: - Redux state management, reducers refactoring, and use of selectors. - React component modernization (class-to-function refactor) and hook usage. - Data fetching resilience (URL search params, fetchAll stabilization) and parameter handling. - Test engineering: test IDs, CI/test suite configurations, and platform-specific test orchestration (Android). - Cross-repo collaboration between app and web modules, with role-based access controls for backend endpoints.
