I delivered a C# tool to identify and eliminate top failing tests. This tool (and a process I developed) affects every engineer on File I/O by reducing the noise of flaky tests.
I delivered JavaScript/KendoUI Validation Dashboard for signing off on monthly releases. This is used by management to assess the risk of a new monthly release.
I delivered a backdoor hybrid C++/C# lock API to enable Excel automation. This API is heavily used by engineers throughout Office to test locks.
