- Developed a windows filter driver in C and C++ 17 for intercepting WDDM callback functions inbound to a third-party GPU driver from the DirectX kernel subsystems; via callback swapping. The driver is based on windows driver model libraries using the windows driver framework (WDF) and some concepts of the windows driver model (WDM). - Setup debug logging in the driver to be usable with the Windbg tool for testing on a VMware virtual machine and the Windows Driver Kit’s TraceView tool for testing on the actual machine. - Configured both physical and virtual environments to allow test driver installation and running via a PowerShell script. - Retrieved data from callbacks to be sent back to an MFC user application using multithreading with spinlocks for data read requests inbound to the driver from the user application. - Implemented a Linux driver for intercepting IOCTL Syscalls from the GPU driver on an Embedded Linux Nvidia Jetson T210; via callback swapping. - Utilized windows profiler on the llama cpp open-source inference engine to analyze the organization solution’s performance. - Wrote Python scripts for generating different test scenarios for LLM optimization. - Implemented a restructuring of the LLM neural network tensors using State value decomposition with NumPy Python script. - Reviewed LLM MMLU benchmark references with the team to enforce consistency in LLM benchmark testing approaches. - Maintained project tracks through OpenProject and application source code tracking using Git source control.
