Software Engineer – Embedded
Kymeta- 6-month assignment:
oI was responsible for the code in the transmitter and receiver units for their beam forming antenna.
oWrote C code for the dual power supply switcher. This would allow the power to switch from one supply to another in milliseconds.
oThe products for Kymeta were using the Yocto build system, using Phytec board systems.
oWhen the customer switched from Seco to Phytec, I did the same tasks all over again, switching to the latest 3.14 Linux kernel that uses the Yocto build system.
Echodyne-6-month assignment:
oI did the PCIe driver integration for multiple cards for their first radar system.
oResponsible for all Linux software 3.16 bringup, including u-boot, kernel and file system
Worked on several proof of concept designs using Raspberry Pi for two customers.
oOne using a CAN bus hat (Sits on top of the RaspPi) that I also configured to be a functioning access point.
oAnother Raspberry Pi used a Pantech UML290 USB 3G data module. For remote communication for the State of Hawaii.
oWorked on the Xilinx Zedboard with the Zync processor. Brought the board up with a headless kernel and modified uboot to boot from my filesystem and image.
oCreated bash scripts for testing and easy setup.
Innovative Advantage June 2013 to June 2014
Software Engineer – Embedded Linux
As the sole Linux engineer on this project, created an embedded Linux operating system for an encoder/decoder expansion card for the Innovative Advantage AVDS (Audio Video Distribution System) avionics.
Using the Arago Linux project for TI DaVinci processors, I built the u-boot, kernel and a very small UBIFS based file system for the card. This OS for the DaVinci was the TI-RTOS
Tuned the system so that the kernel would boot in only 8 seconds, full loading of the entire system firmware only took 15.
