Justin Parma contributed to the coopcycle-app repository by delivering core user flows, modernizing the data layer, and enhancing cross-platform UI theming over a three-month period. He implemented dynamic theming with dark mode, improved keyboard interactions, and stabilized Android layouts to ensure a consistent user experience. Justin migrated critical data fetching to Redux Toolkit Query, replacing legacy hooks and centralizing API interactions for better performance and maintainability. He refactored navigation, introduced context providers, and overhauled initialization logic using JavaScript, React Native, and TypeScript. His work addressed both business value and technical debt, resulting in a more reliable, maintainable, and user-friendly application.

Mar 1, 2025March 2025 — CoopCycle app delivered major data-layer modernization and reliability improvements, focusing on business value, performance, and maintainability. Migrated critical data paths to Redux Toolkit Query (RTK Query) for unassigned tasks, task lists, and stores, replacing legacy hooks with RTK Query slices, memoizing fetch options to reduce redundant calls, and centralizing API interactions to improve consistency and reduce server load. Overhauled initialization and data loading orchestration to streamline first-load behavior, unify loading state management, and improve data freshness across components. Performed cleanup and targeted bug fixes to remove dead code, standardize Redux actions and prop names, and address UI/data-fetching edge cases (e.g., case-insensitive sorting). These changes result in faster, more predictable initial loads, reduced API surface area, and improved developer productivity. Technologies/skills demonstrated include Redux Toolkit RTK Query, React/Redux patterns, useMemo optimization, first-load state handling, loading orchestration, and maintainability/test maintenance.
