During February 2025, Beguene worked on the hirosystems/explorer repository, focusing on frontend development using React and TypeScript. He simplified the Sandbox user interface by removing the deprecated "Save Contract in Hiro Platform" button from the sandbox deployment, a change tracked in a well-documented commit. This update aligned the sandbox environment with production workflows, reducing user confusion and maintenance overhead by eliminating unsupported features. The technical approach centered on cleaning up dead UI paths and improving maintainability. While the work addressed a single feature and did not involve bug fixes, it demonstrated careful attention to platform consistency and codebase clarity.
