Worked on the hirosystems/explorer repository to streamline the Sandbox user interface by removing the deprecated Save Contract button from the sandbox deployment. This change was implemented using React and TypeScript, focusing on frontend development best practices to simplify the UI and align sandbox behavior with the production platform. By eliminating an unsupported feature, the update reduced user confusion and maintenance overhead while improving the maintainability of the codebase. The work was tracked through a focused, well-documented commit, ensuring clear traceability. No bugs were fixed during this period, and the primary contribution centered on enhancing the clarity and usability of the sandbox environment.
