During October 2025, Vasanth Karanam expanded scikit-learn’s platform support by implementing Windows ARM64 continuous integration for wheel builds in the main repository. He developed new runner configurations and updated scripts to accommodate the Windows on ARM (WoA) environment, addressing the lack of Docker support by introducing a Docker-less workaround. Using Shell and YAML within GitHub Actions, Vasanth enabled automated ARM64 wheel builds and tests, improving cross-platform coverage and build reliability. This work reduced release risk for ARM64 users and streamlined validation, reflecting a focused approach to CI/CD and cross-platform development within a complex, production-grade build system.
