Melville, New York, Us

Worked with Hardware Engineers in developing a number of Lighting control products, analyzed hardware performance and identified deficiencies and suggested improvements and cost reduction solutions. Created a development environment for the ST Microelectronics STM32Fxxx series of ARM processors, using Eclipse and GCC. Developed new firmware images to meet the goal of minimal development for hardware and software. Reverse engineered RS485 based Protocol used by the existing design to develop a new lighting control device using STM32F102 processor and FreeRTOS. Developed firmware modules for a distributed lighting control system using a variety of processors. Implemented firmware update including Flash Memory management.

Camas, Washington, Us

Working on device drivers for a proprietary Network switching technology for a startup. Refactored drivers from previous product. Redesigned and reworked driver for Hardware interface. Developed mechanisms to allow support of multiple interface cards by eliminating the use of globals for dynamical allocated control structures. Worked with hardware engineers to test initial implementations of parts of the hardware.

Worked on Linux based board to receive and process network monitoring packets. Low level processing of packets performed by a pair of FPGAs. Worked on device driver for an FPGAs, wrote ioctls to read and write FPGA registers, and manage FPGA configuration tables, to reset and initialize FPGA. Wrote multi-threaded scripted test program. Implementation was designed to be modular to produce test programs for FPGAs, to run both remotely using UDP and locally on the board under test. Developed acceptance test script files, regression test script files as well as other test script files needed by the applications and hardware teams. Tests included sending predefined and generated packets using raw sockets interface over 10G fiber and copper networks. Handcrafting Ethernet packets for ARP, GTP-U/C, CDMA A11/A10, SCTP, and others to generate test cases.

San Jose, California, Us

In a Scrum environment developed firmware for Multitech development board and customer CDMA radio for M2M cloud application. Based on Multitech supplied firmware based on Angstrom (Openembedded and Bitbake). Developed agent to manage communications with HTTP server as well as sensor task to monitor sensors (GPS, board temp, analog input) communicating through agent to send sensor values to server and receive commands from server. Investigated the concept of an “Internet of Things” using a number of 900 MHz 802.15.4 devices, including Mesh routing and 6lowpan.

Upgraded firmware based on SLES 11 SP1 partially upgraded to 64 bit to SLES 11 SP2 fully upgraded to 64 bit. Upgraded source packages to latest versions available ported patches where necessary.

Tasked by Ixonos to help Palm opensource WebOS. Scrub unreleasable code, rationalize code and convert to run under new cleaner build system. Replaced some unreleasable code with new or open-source code. Debugged and completed test suite for WebOS nyx application/system interface.

Worked on Cisco Systems Linux based Consumer/SOHO grade wireless routers. Worked on cleaning up build system to be more parameter driven. Brought new product into build system. Researched design for remote printing solution for portable devices. Debugged samba regarding an issue with Win XP transferring medium file.

Worked on kernel support for Android Power Management. Investigated issues with various third part ports of device daemons and backported drivers that prevented the kernel from fully suspending.

Debugged Device Drivers, Developed Device Firmware updater. Debugged and enhanced BootLoader for Zilog ZA9L0 processor (ARM 922T with security features). Designed two stage bootloader to overcome 40KB limit to add new features and increase reliability. Wrote device driver to read security keys from CPU ROM. Analysed USB communications failures.
