    I graduated from an accredited university with a bachelor's degree in electrical engineering with a GPA of 3.65. Since that point I now have over 10 years experience in various fields of engineering ranging from electric drives to security systems. My primary focus has been with embedded systems and PCB design. I have used numerous controllers in past designs however the most popular with my clients has been the arduino and various versions of it. Also the teensy has been a popular choice lately. I use Eagle Cad to design PCB's and can design up to four layers although two layers will suffice for most projects. I also have have experience with various IOT modules such as the laird bl652, esp8266, and the particle. If you have any questions please contact me.
