Karthick worked on the namma_wallet repository, focusing on front end development using Flutter and Dart. During the month, he delivered two features centered on UI/UX and theming enhancements, specifically improving dark mode reliability and refining the PDF upload interaction. His technical approach involved refactoring the Profile View, targeting ThemeSectionWidget and related components to align with the design system and boost readability. Karthick also addressed user friction by fixing touch areas and toggle behavior, while maintaining code quality through formatting improvements. The work laid a foundation for future theming and feature development, demonstrating depth in UI consistency and maintainability.
