Marc contributed to cross-platform development in the mrousavy/swift and swiftlang/swift repositories, focusing on Android and Swift system compatibility. He enhanced CI documentation by updating README files for better visibility and accessibility, and improved installation reliability by refining command-line flag handling for Swift testing. In swiftlang/swift, Marc implemented 16 KB memory page size support for Android 15+ native libraries, optimizing performance through CMake and linker flag adjustments. He addressed platform-specific issues using conditional compilation and Python scripting, ensuring robust system programming and testing. Marc’s work demonstrated depth in build system configuration, platform compatibility, and continuous integration, delivering maintainable, developer-focused solutions.

July 2025: Delivered memory page size optimization for Android 15+ native libraries in swiftlang/swift. Implemented 16 KB page size support, including build configuration updates and linker flags to optimize memory usage and performance on newer devices. This change is tracked under commit 663ec9340d37b3407c8408b0f822d8d9962162b1 ('Support 16 KB page sizes on Android (#81596)'). No major bugs reported this month; the work enhances cross-platform compatibility and establishes a foundation for continued Android 15+ improvements. Technologies demonstrated include Android NDK memory paging, build system configuration, linker flag management, and disciplined version control.

In May 2025, the swift repo delivered a focused feature to improve the visibility and accessibility of CI status and documentation. The README CI summary table was updated to display all architectures for a host on a single line, enhancing readability and quicker status checks. Accessibility labels were added to CI badges to support inclusivity during GA Awareness Month. This work improves developer onboarding, triage speed, and documentation transparency across architectures.
