Developed and delivered Android Auto integration for the persian-calendar/persian-calendar repository, enabling users to view the Persian Calendar directly within their car interface. Focused on accessibility and cross-device user experience, the work introduced a dedicated Android Auto service and a new screen for in-car calendar display. Leveraged Kotlin and Gradle to implement clean architecture and establish robust data flow, laying the groundwork for future enhancements. The integration required adding Android Auto dependencies and designing UI components tailored for automotive environments. This release addressed platform reach for Persian-speaking users and demonstrated proficiency in Android development, service implementation, and cross-platform feature delivery.
