Raleigh NC ***06



I am currently looking for a small startup environment where I can apply skills I have learned to design and develop a product to solve problems for customers. I am unique situated for a startup in that I capable of doing most all the engineering for a rapid product release including DSP, FPGAs, PCBs, firmware, software, embedded Linux etc. While setting up processes and procedures to grow business as well provide management for other engineers as needed.

Note: I am not currently interested in relocating from the Raleigh NC area
