Jenner contributed to the WebKit/WebKit and oven-sh/WebKit repositories by delivering infrastructure improvements, stabilizing builds, and enhancing test automation for Apple platforms. Over five months, Jenner addressed build failures and CI instability by reverting problematic changes, modernizing CI infrastructure to Apple Silicon, and updating asset management for new OS versions. Using C++, JavaScript, and Python, Jenner implemented solutions for deprecation handling, Unicode robustness, and layout testing, while also improving accessibility in test result dashboards. The work demonstrated depth in debugging, configuration management, and cross-platform development, resulting in more reliable builds, faster feedback cycles, and improved test coverage across multiple Apple environments.

WebKit/WebKit — 2025-10 monthly summary: Focused on unblocking VisionOS CI/builds and stabilizing the iOS test CI. Delivered a temporary workaround to unblock VisionOS builds by wrapping deprecated declarations in WKFullScreenWindowControllerIOS.mm, enabling CI progress and faster feedback. Stabilized the iOS test suite and CI through targeted test gardening, regression reversions, and suppression of flaky tests, restoring reliability for API tests and WK tests. Result: improved CI throughput, reduced blockers, and accelerated platform-specific change delivery. Demonstrated proficiency in debugging native code, build-system troubleshooting, test gardening, flaky-test isolation, and cross-platform collaboration (VisionOS/iOS).
