Worked on improving UI reliability and frontend consistency in the MapStore2 repository, focusing on resolving a critical issue affecting the Snapshot Panel. Addressed a bug where incorrect className usage in SnapshotPanel.jsx led to inconsistent button styling and impaired functionality, which impacted user experience and design alignment. The solution involved updating the className attribute to restore proper button appearance and behavior, ensuring compliance with established design guidelines. Collaborated with another contributor using Git-based workflows to deliver the fix. Utilized JavaScript and React throughout the process, demonstrating attention to detail in front end development and commitment to maintaining codebase quality.
