PROFILE
Andy Bartholomew
Andy Bartholomew contributed to the airbnb/lottie-ios repository by building foundational improvements in animation networking and testing reliability. He introduced a LottieURLSession protocol in Swift, centralizing network configuration for Lottie animations and enabling global control or disabling of network requests, which improved testability and reduced regression risk. Andy also developed a deterministic snapshot testing mode by adding ReducedMotionOption.disabledMotion, allowing static rendering of animations to eliminate nondeterminism in tests. His work demonstrated depth in iOS development, animation handling, and testing strategies, resulting in more reliable CI pipelines and streamlined network behavior management across 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.
