Worked on stabilizing Docker builds for macOS in the iggy-rs/iggy repository, focusing on resolving a persistent build failure that impacted cross-platform development. Addressed the issue by updating the Dockerfile to use a rust:${RUST_VERSION}-slim-bookworm base image and removing musl-dev, which enabled targeting GNU/glibc and eliminated symbol errors related to __aarch64_ldadd4_sync. This fix improved reliability for both local and CI environments, reducing build flakiness and streamlining the developer workflow. Leveraged skills in containerization, DevOps, and Rust to restore a dependable Docker-based development process, ultimately enhancing productivity and compatibility across different operating systems.
