Worked on the airbnb/lottie-ios repository to enhance animation network configuration and testing reliability using Swift and iOS development skills. Introduced a LottieURLSession protocol and integrated it into animation loading, enabling centralized control over network requests and improving testability by allowing global configuration or disabling of network access. Later, delivered a deterministic snapshot testing feature by adding a disabledMotion mode to the ReducedMotionOption, which renders animations statically for snapshot tests and eliminates nondeterminism. This approach improved CI stability and accelerated pull request validation, demonstrating a focus on robust animation handling, test reliability, and collaborative development within the Lottie animation ecosystem.

Dec 1, 2025December 2025: Delivered foundational networking improvements for Lottie animations by introducing a new LottieURLSession protocol and integrating it into the animation loading path. Added LottieConfiguration.defaultURLSession to enable global configuration or disabling of network requests, improving testability, consistency, and flexibility across the Lottie ecosystem. This work reduces regression risk and simplifies network behavior changes across apps.
