I develop the product tests & automated test system tools for manufacturing hardware and assembly validation. I develop the analysis tools to support tests for digital & analog video, digital & analog audio, Bluetooth/BLE, network communication, serial communication, touch screen input accuracy, data collection, and various other support technologies. I develop tools based on the Windows platform and make use of Windows .NET API tools for directshow, WASAPI, Windows multimedia device libraries and various other control interfaces. I support AV products with embedded Linux & FPGA cores and have a working knowledge of those systems for the purpose of controlling data for device validation.
