PROFILE
Jeromy Statia (from Dev Box)
During three months on microsoft/CoseSignTool, Jstatia delivered foundational enhancements to COSE signing infrastructure, focusing on secure key management, plugin extensibility, and robust certificate handling. He implemented chained COSE header extenders and modernized authentication by migrating to token-based environment variables, reducing secret exposure. Jstatia improved cross-platform reliability by addressing Unix path handling and macOS architecture issues, while also stabilizing NuGet packaging versioning in CI/CD workflows. His work, primarily in C# and YAML, included comprehensive unit testing and documentation updates, resulting in more reliable builds and streamlined developer onboarding. The depth of his contributions strengthened security, maintainability, and integration for downstream consumers.

Aug 1, 2025August 2025 (microsoft/CoseSignTool): Focused on stabilizing NuGet packaging versioning in CI/CD. Implemented propagation of the VersionNgt version through the .NET publish and NuGet pack steps and standardized removal of a leading 'v' from version tags to ensure consistent artifacts and metadata. Result: more reliable package builds, reduced versioning-related failures, and improved reproducibility for downstream consumers.
