Worked on the multiversx/mx-contracts-rs repository to enhance the reliability of the continuous integration process by stabilizing the CI workflow and improving release versioning. Addressed build determinism by pinning the Rust toolchain to version 1.86 within GitHub Actions, ensuring that builds remain consistent across environments. Updated the release artifact image tag from v9.0.0 to v10.0.0, which contributed to more predictable and reproducible releases. Leveraged skills in CI/CD automation, YAML configuration, and release engineering to reduce CI flakiness and streamline contributor onboarding, ultimately supporting faster and more dependable development cycles without introducing new bugs during the period.
