Responsible for platform software on the company's next generation firewall product.

• Platform Software Tech lead on Cisco's $4.5B/yr Catalyst switching product line; fastest Cisco program to ramp to $1B

• Startup member of a new product team which designed, developed and delivered the ASR1000 family of 5-200Gbps edge routers. ASR1k represents over $1B/yr revenue.

• SW Technical lead for several custom datapath bridge ASICs. Developed Linux device driver firmware, configuration and exception handlers for these devices, running on Freescale MPC85xx and Intel x86 processors

• Developed boot firmware for several generations of Intel x86 processors (Wolfdale, Jasper Forest, Ivy/Sandy Bridge, Broadwell-DE) running Insyde SW’s uEFI BIOS as well as on Freescale PowerPC MPC85xx processors.

• Individual contributor on many chassis management and infrastructure enhancements (including SPI4, PCIe, commodity device drivers such as SPI, I2C, USB...) as well as customer escalation teams

• Platform Software Team lead for the Catalyst 9300-Gen2 refresh effort

• Technical lead for Cisco’s first deployed “Secure boot” trusted platform ecosystem

• Technical lead for environmental monitoring (temp, voltage, fans) for a metro Ethernet switch

• Developed firmware for the Intel IXP1200 and IXP2800 network processors running in an internet security appliance. This included both NPU microcode as well as Linux device driver and board initialization, boot firmware, upgrade utilities and diagnostics.

• Developed micro controller software, Linux device drivers and an FPGA for a environmental monitoring blade

• Member of initial startup team

• Voicepath architect and lead DSP firmware engineer responsible for developing a packetized voice media gateway. Developed/integrated audio codecs, echo cancellation, jitter buffer firmware. Oversaw telephony conformance test efforts.

• As the platform software group manager, led a team of 6 engineers responsible for OS, board support packages, network device drivers and DSP firmware

• Member of initial startup team

• Lead DSP firmware engineer responsible for the development of a GSM (Global System for Mobile Telecommunications) digital microcellular basestation/switch product line in a demanding startup atmosphere.

• DSP firmware design and development of the transcoder and rate adapter functions, the GSM Enhanced Full Rate (EFR) vocoder, data and fax rate adaptation and frame processing. Also responsible for implementation of DSP DTMF/Cadence generation and R2 Signalling MF tone generation and detection modules, radio subsystem support and RF interface drivers.

• Lead engineer responsible for developing firmware based calibration methods to allow compliance to very stringent radio interface standards.

• Engineering liaison to manufacturing for issues related to the TRX radio subsystem, voice path problems and unexplained phenomena
