Comfortable shipping quickly with tight customer feedback loops, he combines a strong automation/build-engineering background with platform and payments experience. An active contributor to high-profile .NET repos (corefxlab, msbuild), he has a proven knack for fixing build, packaging, and CI/CD pain points that accelerate releases. With an MS in Computer Science from the University of Washington and roots in backend and reliability work across Azure, Power BI, and commerce systems, he blends deep technical credibility with product-focused leadership.
