Pursuing my passion through various hardware/software projects.

Continuing to contribute OS kernel engineering at Intel's Microsoft Technology Center.

Working at Intel's Microsoft Technology Center on Core OS & ISA.

Very cool startup in stealth mode being run by Seamus Blackley (XBOX) - poor timing w/COVID-19 quarantine.

Windows Kernel Graphics - designed and implemented VAIL, changing components owned by several teams across Windows. This is used for different types of guest virtual machines to have hardware accelerated rendering that stays in graphics memory.

Returned to the Operating Systems Group at Microsoft to help ship Windows 10! Worked on the high DPI problem space, built a new mechanism to allow developers to more easily make their apps scale on high DPI monitors.

Took a short sabbatical after trying out a startup working for Brian Valentine (Windows).

Hired during Windows Vista to help work on a new technology to “bring the Windows desktop into the 21st century.” Helped design and write the DWM – Desktop Window Manager – which is responsible for desktop composition – allowing several visual effects to be done, notably the glass look. My experiences during this job have been many, keeping me challenged and entertained. I’ve done everything from building the hosting process for the window manager and wiring in its subsystem startup architecture to retrofitting support in GDI for device managed bitmaps to be selected into multiple DCs at once, allowing window back buffers to exist in video memory. I’ve debugged and fixed countess application compatibility problems, mostly without source code access. I’ve built emulation technologies that we still use, which allow an application designed for a noncomposed desktop to function seamlessly on a composed desktop – with regards to painter’s order versus clipped painting. I’m considered the best ‘painting’ debugger in my group, through the whole stack down to the hardware, and I’ve served as a hired gun for several non-Windows teams to debug last-minute issues with painting in their applications. My contributions to Windows are many. Here are a few of my contributions to Windows 8: o Debugged and fixed over 140 bugs in the last year. o Smooth Rotation Architecture and Performance – debugging and optimizing the whole display mode change stack, I was able to save over 600ms of time and give it back to applications during display mode change. Wrote the code to animate between display orientations. o Added support for Direct2D rendering primitives in our compositoro New Security Architecture – matured a technology called ‘virtual accounts’ to support interactive tokens, modifying subsystem support to allow our window manager to run as a special token, and be able to compose all desktops in the session.o Implemented per-monitor DPI scaling in Windows 8.1o DWM on XBox/Holo

Responsible for assisting in critical parts of software development in the games and applications areas, designing several technologies to enhance the Windows experience based on reverse engineering and debugging. Developed a technology that rivals Microsoft’s Detours, supporting API hooks in even tighter scenarios.

Worked on several products throughout the company (both games and applications), and came up with my own software products (WebBlinds, PocketBlinds, BootSkin). Contributed a large amount of work to WindowBlinds and DesktopX.

Designed an e-commerce backend to handle software purchase and serial number generation. Built several websites and technologies which allowed us to host user-developed content for our software (skins) as well as software to visually represent live sales statistics. Basically responsible for web services during this time.

I was the one and only tech support guy at the company for a year. Started writing software in my spare time, which turned into enhancing our back end e-commerce software to tackle order and support issues.
