In May 2025, AJ McCarthy enhanced the utat-ss/finch-flight-software repository by implementing build hardening across the obc, eps, and pay applications. He configured the build system to treat all compiler warnings as errors, ensuring that any warning would cause the continuous integration pipeline to fail. This approach, using C and Kconfig within embedded systems, established a consistent standard across multiple repositories and improved code quality by reducing the risk of warning-driven defects reaching production. By standardizing compiler warning policies and build configurations, AJ enabled faster remediation of issues and contributed to more reliable and maintainable embedded software development practices.
