• Revamped native DirectWrite test infrastructure to be XML-driven in order to accommodate the large expansion of fonts included in Windows Phone 7; investigated and tested font cache performance.• Ported and maintained approximately 360,000 test cases in 600+ test jobs which were used to verify the following: Windows Phone 8 D3D9 runtime and drivers, Windows Phone Blue D3D11 runtime and drivers. Test code consisted of 600+ source files spanning the gamut of Direct3D… Show more • Revamped native DirectWrite test infrastructure to be XML-driven in order to accommodate the large expansion of fonts included in Windows Phone 7; investigated and tested font cache performance.• Ported and maintained approximately 360,000 test cases in 600+ test jobs which were used to verify the following: Windows Phone 8 D3D9 runtime and drivers, Windows Phone Blue D3D11 runtime and drivers. Test code consisted of 600+ source files spanning the gamut of Direct3D functionality.• Analyzed test failures in the above suites (starting at 60000+) and drove efforts with Qualcomm to get driver issues fixed via regular conference calls. We released with zero failures.• Acted as the graphics team security czar; performing regular threat models of graphics feature code.• Skills gained and/or utilized include: C++, C#; Powershell; WinDbg user and kernel mode debugging; Direct3D; DirectWrite; fonts; Imaging Codecs; Windows Phone App development; Show less

Windows Mobile Multimedia Test Team• Created streaming audio and video test sinks for DirectShow testing. These parsed ASF & MPEG files, created in-memory objects representing stream packets which were then compared with actual stream output when status changed due to seeking, rewinding, etc.• Created a generic fuzzing framework used to fuzz test millions of image, audio and video files as well as http headers.• Created targeted fuzzers for ASF (WMV, WMA) and ISO (AVI… Show more Windows Mobile Multimedia Test Team• Created streaming audio and video test sinks for DirectShow testing. These parsed ASF & MPEG files, created in-memory objects representing stream packets which were then compared with actual stream output when status changed due to seeking, rewinding, etc.• Created a generic fuzzing framework used to fuzz test millions of image, audio and video files as well as http headers.• Created targeted fuzzers for ASF (WMV, WMA) and ISO (AVI, MPEG,MOV,etc) which would strategically seed fields with bogus data based on XML templates. This greatly enhanced effectiveness of fuzzing versus random fault injection and resulted in several bugs.• Created an extensible metadata parsing library used by several testers to verify correct metadata processing / creation of media components.• Created a generic image comparison library used by much of the division for validation of screenshot renderings versus baseline images.• Skills gained and/or utilized include: C++; XML; threat modelling; media codecs and streaming; file fuzzing techniques Show less
