Donal McCarthy contributed to the paritytech/ahm-dryrun and related repositories by building and refining automation, licensing, and integration workflows over six months. He implemented submodule-based Polkadot SDK integration, enhanced build scripts for Westend dry-run reliability, and managed Paseo runtimes dependencies to ensure reproducible builds and smoother upgrades. Donal’s technical approach emphasized maintainability, using Git, Shell scripting, and YAML for CI/CD configuration and environment management. He also improved documentation and UI clarity, reducing onboarding time and user confusion. His work demonstrated depth in DevOps, submodule management, and technical writing, resulting in more stable, maintainable, and legally compliant development processes.

May 2025 Monthly Summary (paritytech/ahm-dryrun): Delivered a targeted build-process enhancement to enable a reliable Westend dry-run using ZB, ensuring the correct runtime artifacts are built and copied for Westend and Asset-Hub Westend. Implemented alignment with Oliver's build branch to streamline testing and reduce handoff friction. This work reduces build/test cycle times, improves reproducibility across environments, and strengthens the Westend integration surface (artifact handling, branching workflow, and script reliability). Technologies/skills demonstrated include build scripting optimization, environment-specific artifact management, and branch-based workflow practices.
