Austin, Texas, United States

Technical lead in the Universal Software Radio Peripheral (USRP) product line, an open source family of software-defined radios.- Re-architected streaming code for USRP Hardware Driver (UHD) to improve performance. This has allowed users to take advantage of the full RF bandwidth of several USRP models which were previously bandwidth-limited by UHD streaming capabilities.- Leads a portion of a large team of software developers in the design and implementation of driver software support for a new generation of USRP devices.

Austin, Tx

Technical lead in program to create a new product line of digital test instruments for the semiconductor test market. The PXI 6570 and PXI 6571 Digital Pattern Instruments added ATE-class digital capabilities to NI's offerings, a crucial component of NI's Semiconductor Test System (STS).- Defined instrument API and data format for specification of digital patterns and digital edge timing parameters.- Led a software team in the design and implementation of kernel driver, instrument API, and calibration routines. - Coordinated collaboration of driver software team with HDL developers, hardware developers, manufacturing test, hardware V&V, and application software teams.

Austin, Texas Area

Technical lead in program to create NI's first Vector Signal Transceiver (VST), an award-winning new product line that became the most successful PXI product by revenue in NI's history. The VST combines a vector signal analyzer and generator with a user-programmable FPGA and high-speed digital interfaces for real-time signal processing and control.- Grew driver software team from a single member to 20 developers at its peak. - Led the design and implementation of driver software, instrument calibration, and libraries of FPGA IP that enable users to customize the digital logic in the instrument. - Co-inventor on US patents related to enabling users to customize FPGA logic in test instruments. The method of FPGA customization pioneered in the VST was subsequently adopted by several product lines at NI, including oscilloscopes, waveform generators, digital pattern instruments, and software-defined radios.

Austin, Texas

Senior software developer in RF instrumentation team at NI. Led implementation of driver software for some of the early offerings by NI in the RF market.- Defined NI-RFSA instrument API for RF signal analyzers.- Led software development of NI's first RF signal analyzer in the 6 GHz frequency range (PXI 6553). Worked closely with the hardware development and V&V teams in the newly created NI Santa Rosa office.- Designed and implemented RF calibration for 6 GHz signal analyzer, including amplitude accuracy, temperature correction, and digital equalization.

Austin, Texas

Driver developer for high-speed digital interfacing PXI products.- Developed kernel driver and implemented instrument API for high-speed digital I/O interfacing instruments.
