* Designed and maintained codecs for wireless video systems. Developed an FPGA based H264 video decoder. Integrated Mpeg2/H264 decoders into wireless product. Supported, optimized, and enhanced Mpeg2/H264 encoders developed while at Duma Video. Created complete decoding solution in Altera FPGA by integrating an on-chip NIOS processor, DDR3 memory interface, ASI serializer/deserializer, and 3rd party Ethernet and HDMI interfaces. * Maintained and updated FPGA based DVB-T Modulator/Demodulator wireless designs. The Modulator and Demodulator were designed using a Matlab - Simulink - System Generator design flow and implemented on Xilinx FPGAs with Vivado.

* Leadership - As a part owner and executive, I forged business relationships and executed roadmap decisions, license agreements, and customer support solutions. I facilitated open communications between sales and marketing, engineering, and manufacturing team members and made sure each person had the guidance and tools needed to be successful. * Technical - My engineering responsibilities at Duma were all encompassing. I designed video codecs (Mpeg2/H264 compression and decompression) in FPGA ICs using VHDL rtl. I also designed numerous functional modules and I/O standards such as: ethernet streaming interface, video scaling, color space converter, licensing functionality, closed caption, audio, FPGA standalone programmer, on screen display, PCI, PCI-X, SDRAM, DDR, DDR2, I2C, I2S, Component/Composite, ASI, SDI, DVI, HDMI, DSP, LCD display, OLED display, and others, including many custom interfaces. In addition to FPGA chip programming, my other engineering responsibilities included: system design architecture, GUI development using Visual Studio, c-based video stream analysis tools, embedded software and driver modifications, schematic design review and support, mechanical design support, and circuit board debug and test.

* Created diagnostics and calibration SOC solutions for large scale unix based automatic test equipment with 1024 test pins. Success in this position required comprehensive understanding of the large scale tester, solid understanding of schematic design, layout, analog and digital tools, component specifications, c-coding, Verilog, perl scripts, Clearcase, and extensive code and board level debugging skills. * Analog Calibration - Lead engineer tasked with creation of calibration software for the mixed signal instrument tester. Test components included A/D, D/A, PMU, Gain/Attenuation stages, level drivers, and waveform generators. Assisted with hardware design circuitry to guarantee accurate calibration results.* Digital Diagnostics - Created diagnostic software for quickly locating and fixing faults on the digital IC test head. Diagnostics included components such as DDR memories, level drivers, pin connection matrix, voltage and ring clamps, and timing skew.* Wireless Calibration/Diagnostics - As the lone engineer assigned to calibration and diagnostics of the RF IC tester, worked independently and succesfully implemented the testing requirements. Calibration of the tester was accomplished using the 12-term 2-port error correction algorithm, as well as using the Y-factor method for noise.

Initiated my career designing ruggedized handheld wireless computers. Designed minor functional blocks including power supply circuitry and LCD display driver. Helped in diagnostic of RF faults and interference. In charge of researching and selecting electrical components for new computer architectures. Assisted in pinpointing fault areas of the laptops by repetition tests, drop-test, and water submersion.
