PROFILE

Bert Belder

Worked on enhancing Windows development workflows and release reliability across microsoft/git and denoland/deno repositories. Delivered features to improve symlink handling in Windows, including refactoring phantom symlink creation for better code reuse and adding targeted tests to increase CI coverage. Introduced explicit symlink type specification for cross-platform consistency using C and Git. In denoland/deno, implemented secure Windows binary code signing with Azure and automated release workflows using GitHub Actions and YAML, isolating Windows targets to reduce release failures. Updated artifact signing conventions in CI/CD pipelines to align with evolving standards, ensuring maintainable, secure, and reliable build and release processes.

October 2018 Microsoft/git monthly summary focused on Windows symlink reliability improvements and cross-platform consistency. Key work includes a refactor to move phantom symlink creation into a dedicated function to boost code reuse and testability, and the introduction of explicit symlink type handling for Mingw via .gitattributes to reduce reliance on heuristics. Additionally, Win32 symlink coverage was expanded with tests for the symlink attribute to verify correct resolution across scenarios, enhancing testability and CI reliability. These changes collectively reduce checkout risks on Windows, improve cross-platform behavior, and strengthen overall code quality through consistent signing and review.
