Architecture
Created a React-based Single Page Application (SPA) for end-to-end podcast streaming using functional components and TypeScript, following a modular, component-driven architecture with route-based code splitting to improve client-side performance.
Implemented a custom audio playback system using the HTML5 Audio API with event-driven state management, enabling smooth playback controls, responsive UI updates, and a noticeably faster load-to-play experience by approximately 25%.
