Career Experience

I’m an independent consultant with experience in projects using 8 and 32 bit microcontrollers, mobile application processors and embedded single board computers.

Embedded Linux Experience:

• Successful board bring up of several fully custom boards mostly centered around Texas Instruments OMAP3 and OMAP4 processors.
• Low-level Android modifications with Ice Cream Sandwich (ICS) and Jelly Bean (JB)
• Extensive boot loader (u-boot and x-loader) customization and integration
• Extensive Linux kernel modifications to support custom boards and customer requirements
• Modifications range from customized boot configuration to full custom driver development
• Pro-actively implement forward looking solutions that track the direction of the open source upstream Linux kernel to enhance functionality as well as simplify kernel upgrade effort in the future
• On the fly competent hardware troubleshooting, diagnosis, and corrective action for early board spins
• Assist in hardware design by recommending enhancements drawing upon past experience and excellent understanding of boot loaders and low-level kernel hardware interfaces
• Development of a low-level user-space software interface to abstract away hardware details and enable re-use of higher level software on different hardware, projects, and products
• Experience assembling build environments constructed around Open Embedded and its derivatives (Angstrom, Arago) in an intelligent and user friendly manner
• Heavily leverage git source code management repositories to manage internal projects and stay synchronized with upstream repositories
• End of line factory deployment and testing applications

Embedded Experience:

• Atmel AVR 8-bit microcontrollers and Cortex-M3 STM32 32-bit microcontrollers
