I integrated real-time location tracking, ride requests, and driver-partner communication functionalities using MapKit and Core Location frameworks to mimic the core features of the Uber platform;• For Instagram, I aimed to recreate its immersive photo and video sharing experience. I implemented a visually appealing and intuitive user interface consistent with Instagram's design principles. Leveraging Core Data for efficient content management, I optimized performance for seamless media browsing and implemented features such as photo filters, stories, and direct messaging to replicate the essence of the original app while prioritizing data privacy and security.
