About

My background in engineering is rooted in both product development and new emerging technologies where I have acquired a number of skills that lead me to success in my engineering tasks. Most of my career tasks have required I wear several hats ranging from mechanical design through hardware design to PCB design. I like working on new concepts where I get to use my skills to bring a new innovative idea to reality.
