Fliff is a social sportsbook app where sports fans make picks on spreads, totals, and parlays, climb leaderboards, and compete with friends.
- Used GraphQL and Swift concurrency (actors and async/await) to power real-time live data updates free of data races.
- Built SwiftUI components with Lottie and built-in animations to create engaging, dynamic interfaces.
- Implemented URL-based routing for consistent navigation across the app, supporting push notifications and universal links.
- Improved scroll performance on data-heavy screens with thread-safe image caching and asynchronous loading.
