Worked on the kindfi-org/kindfi repository to deliver a feature that enables persistent user engagement in the project detail view, focusing on comments, likes, and follows. Leveraged JavaScript and TypeScript within a React and Node environment to synchronize frontend interactions with backend data models, ensuring reliable metrics and consistent user experience. Integrated Supabase-based session validation to secure user actions and prevent unauthorized interactions, aligning UI components and API endpoints with updated data structures. The work emphasized backend data integrity and seamless UI/API alignment, resulting in a smoother, more secure user experience without addressing bug fixes during the development period.
