Worked on the pet-ads/systematic-front repository to enhance front-end maintainability and reliability by streamlining application context management. Addressed a context duplication issue by removing a redundant AppProvider and consolidating state under a single StudySelectionProvider, establishing a unified source of truth for the app. Applied targeted codebase cleanup in App.tsx and ArticlesTable, reorganizing imports and routes while refining components such as Collapsed.tsx and SelectedArticles.tsx to improve readability and onboarding. Leveraged React, TypeScript, and the Context API to reduce runtime risk and lay the groundwork for faster, safer feature development in future iterations of the project.
