Developed and delivered two core features for the Nutrihelp-web repository, focusing on enhancing user engagement and interface consistency. The work centered on implementing a hydration tracking system with reminders and visual feedback, allowing users to monitor daily water intake and persist data using localStorage. UI components were aligned with design tokens and Figma specifications to ensure visual consistency and reduce drift across the application. Utilizing React, JavaScript, and CSS, the developer integrated client-side state management and design-system-driven styling. No major bugs were reported during this period, reflecting a focus on maintainability, user experience, and robust front end development practices.
