Worked on the Concordium/concordium-node repository to enhance the reliability of the macOS notarization process by developing an automated retry mechanism for handling transient network failures during builds. This feature, implemented using bash scripting and devops practices, reduced manual intervention and improved the stability of the continuous integration pipeline. By addressing intermittent network issues, the solution increased the success rate of notarization and minimized build interruptions, contributing to more reliable macOS deployments. The work focused on strengthening release engineering workflows and ensuring that the notarization process for Concordium-node is resilient, efficient, and better suited for production release cycles.
