Worked on enhancing the Citation Management System within the microsoft/Teams-AdaptiveCards-Mobile repository, focusing on both user experience and architectural simplification. Delivered a feature that enables bottom sheet presentation of citation references, improving how users interact with citations in the app. Refactored the citation manager to allow external modules to invoke its functionality, introducing new presentation and building classes while removing legacy code to streamline maintenance. The work was implemented using Objective-C and leveraged skills in UI design and iOS development. This targeted feature addition and architectural update improved integration capabilities and reduced technical debt within the codebase during the project period.
