Continuing work from Starent Networks as it was acquired by Cisco Systems.

Working on proprietary hardware and software multimedia core platforms allowing the mobile internet to be possible.

Technically led a team of 5 engineers responsible for all driver development and a portion of kernel work spread over 5 boards while providing tier 3 product support. Technologies used: Linux 2.6, PPC MPC8548E, FPGA, PCI, ‘C’, SCSI, Fibre Channel, U-Boot• Assisted in the design and architecture of a new generation, modular video server blade with multiple 10 Gbps Ethernet, 4 Gbps Fibre Channel, and 1 Gbps Ethernet interfaces.• Designed driver for Flash platter chipset and new 10 Gbps streaming trick engine chip.• Directed the driver design for many FPGA chip designs.• Increased storage subsystem performance by 30%. Implemented changes in Fibre Channel Controller chip driver, controlling application and tuning of the storage system.• Designed software that allows the video server to detect unique ECC events and disable bad memory cache locations to prevent corruption of the assets. Motorola did not to pursue patent application request.

Developed and maintained many device drivers, and Linux kernel along with providing tier 2 product support. Technologies used: Linux 2.4, PPC 440GP, FPGA, PCI, SCSI, Fibre Channel, I2C, ‘C’, PIC (Microchip), PPC-Boot• Designed, implemented, & tested driver for in-house SCSI storage offload engine chip also requiring modification of kernel SCSI Generic driver and third party Fibre Channel controller chip.• Designed, implemented, & tested driver for the second generation video streaming engine FPGA. • Integrated, supported, and patched Fibre Channel driver for Agilent Tachyon XL2 controller chip. Improved robustness and stability of the driver. Later driver releases contained many of my improvements.• Evaluated and integrated storage systems via extensive testing and tuning them for optimal performance with the video server. Some vendors were Apple, Nexsan, EMC, and Infortrend.

Lead software engineer for the valve group, which designed complete valve systems to control pressure for many manufacturing processes. Solved various problems including: OS/Task and system timing issues, proprietary control algorithm, motor control, and valve performance. Projects included:• Prototyped next generation controller built on a TI ARM7/DSP dual core processor. Created system schematic and got a set of prototype boards up and working including hardware fixes. Environment: GCC/Cygwin• T3BI (new integrated butterfly valve): Implemented temperature driver, designed to handle multiple configurations with one binary, implemented DeviceNet compliance, • Adapted software for a new exhaust pressure controller (EPC) included: processor IO changes, new CO-pro for motion, new features, new RS-485 protocol. I developed a quick GUI in Visual Basic to save typing the commands through Hyper Terminal. App migrated to manufacturing, and other products with serial interfaces.

Designed and implemented chassis management functions for a Metro-Core Optical Networking box. I started 10 months after the company was founded as employee number 53. Responsibilities:• Drivers: I2C, Dallas-1721 thermostat, LED, Disk On Chip from M-Systems (along with dosFs for vxWorks), FPGA driver layers• Chassis Management: This included the design and implementation of module discovery and method for identification, environmental monitoring and control, control card redundancy negotiation and the required configuration, and the control cards booting. The implementation required me to handle hardware interrupts as well as the high level controlling applications. I also created an API for other apps to access chassis related information.

I worked on embedded software for a scaleable core router capable of 1.3 terabits per second throughput.• Reviewed/solved software bugs: dealing with LED management related to various levels of PPP link and SONET status and traffic activity on a line card with OC-48 ports, fabric board initialization and configuration, as well as various card and process crashes• Development environment is Linux/Sun based, ClearCase, GNU Debugger, and the Motorola MPC860T controller.

• Designed embedded software for a new Programmable Logic Controller (PLC) platform using hardware co-designed with a company in Japan. • Participated in architecture definition of a new I/O system platform using open standards and protocols. Required evaluating competitor’s products, traveling in US and in Europe to evaluate and recommend potential outsourcing partners and products, writing of specifications, and prototyping. • Lead architecture of OS redesign structure and device drivers to be more flexible, reusable, modular, and easier to maintain for current and upcoming projects. Involved testing efficiency of different compilers using same C and C++ Object Oriented implementations.• Enhanced and tested a software application used to program the Human machine Interface (HMI) portion of a PLC using MS Visual basic 4.0, Sheridan Software Systems Data and Designer Widgets, and MS Access.
