Worked on stabilizing cross-platform builds for the Kotlin/kotlinx-atomicfu repository by addressing issues related to Kotlin/Native KLIB cross-compilation. Focused on build configuration using Gradle, the developer disabled KLIB cross-compilation through gradle.properties, setting kotlin.native.enableKlibsCrossCompilation to false. This change prevented build failures when cinterop was compiled on non-host systems, which had previously caused non-deterministic behavior in CI and development environments. By resolving this bug, the work improved build reliability and reduced flaky CI runs for multi-platform consumers of atomicfu. The approach demonstrated skills in Gradle property management, Kotlin/Native cross-compilation handling, and systematic issue resolution within build systems.
