Senior🎓
Top SchoolPercy Tierney is an experienced Windows application developer and test engineer with over a decade of hands-on work across kernel, driver and user‑level APIs, having contributed to and shipped more than a dozen Microsoft Windows releases. He blends low-level systems expertise (WDK/WHCK, drivers, Media Foundation, DirectShow, USB/FireWire) with higher-level UWP/.NET app development—publishing consumer apps in the Microsoft Store and maintaining source on GitHub. Percy has driven certification and test programs for ARM SoC tablets and Surface-class devices, created a virtual webcam simulator that reduced hardware costs and earned patents, and influenced WDK samples that were reintegrated into public releases. Fluent in C, C++ and C# with working Spanish, he’s comfortable moving between embedded multimedia testing and shipping polished user experiences.
