During February 2025, Tsrn contributed to the SE4CPS/PlantWaterSystem repository by developing a functional user authentication login page, focusing on both usability and security readiness. The work involved building a responsive React component with TypeScript, supporting email/password and Google Sign-In options, and ensuring the interface reflected Sproutly branding. Tsrn addressed styling regressions by relocating CSS files and updating import paths, which improved maintainability and reduced UI inconsistencies. By leveraging CSS styling and frontend development best practices, Tsrn established a solid foundation for future authentication enhancements, demonstrating a thoughtful approach to component structure, responsive design, and code organization within the project.
