Worked on the medusajs/medusa repository to address a React render crash in the Product Media Gallery, specifically when deleting the last image from a gallery. Applied defensive programming techniques in TypeScript and JavaScript, introducing index clamping and guard clauses to prevent undefined access during UI updates. This approach ensured the gallery transitions smoothly to an empty state without errors, improving stability for merchants. The solution was delivered as a dashboard patch, accompanied by manual verification across single-image and multi-image scenarios. Demonstrated strong front end development skills, focusing on robust UI state management and changeset-based release workflows within the project.
