Worked on the Frontify/brand-sdk repository to enhance API surface stability by deprecating legacy dialog close commands within the app-bridge-theme package. Focused on forward-compatibility, the developer introduced a deprecation pattern for the closeSearchDialog and closeAiBrandAssistantDialog commands, clearly signaling their removal in a future major release to minimize breaking changes for downstream integrations. This approach allowed teams to prepare for upcoming API changes while maintaining roadmap alignment. The work was implemented using TypeScript and front end development practices, emphasizing maintenance and long-term stability rather than immediate feature expansion or bug fixes during the period covered by this profile.
