During June 2026, contributed to the skkuding/codedang repository by implementing a mobile-friendly Create Problem button within the MiddleBanner component. This work involved restoring previously commented code and refining responsive styling to ensure the button’s size and typography fit mobile layouts without impacting desktop views. Addressed a mobile visibility issue so the button appears only on intended mobile screens, directly improving the problem-creation flow for mobile users. The solution was developed using React, Tailwind CSS, and TypeScript, with clear commit traceability and collaboration. The focused feature work enhanced mobile usability and aligned with project requirements for responsive frontend development.
