  Mountain View, CA San Francisco, CA Platforms: Brought up our Debian-based operating system on new switching platforms starting with a JTAG debugger. Over time we evolved into working with hardware vendors on their own u-boot/ONIE ports, using ACPI on x86, and generally reducing the effort required to bring a new platform to our OS. Pluggables: Spent lots of time dealing with Ethernet phys and switching ASICs (typically Broadcom or Mellanox) to support SFP/QSFP devices from 100Mbit to 100Gbit.

Pluggables: Spent lots of time dealing with Ethernet phys and switching ASICs (typically Broadcom or Mellanox) to support SFP/QSFP devices from 100Mbit to 100Gbit. Resolved physical layer issues on new hardware and at customer sites. Other jobs were varied. I fabricated antenna stands, set up racks of hardware in the lab, did a few conference talks.

  Foster City, CA Web Applications: I started on PrintMe where I worked on a variety of web applications and tools. The PrintMe system was based on Apache, Perl, Mason, and Oracle. Embedded Systems: I worked on an automated network-attached billing system for copiers. I primarily dealt with two embedded devices that reported copier usage across either IP networks or the AMPS cellular control channel. These devices were based on PIC microcontrollers and the Nucleus embedded RTOS.

I primarily dealt with two embedded devices that reported copier usage across either IP networks or the AMPS cellular control channel. These devices were based on PIC microcontrollers and the Nucleus embedded RTOS. Finally, I spent some time working on EFI's Fiery embedded printer controllers. These controllers were embedded in copy machines, x86-based, and ran Linux. Show less
