Freelance Extjs4 developer in Broomfield, United States

Front-end Software Engineer

My expertise lies in the realm of front-end software engineering as that is my primary source of income. That being said, I often take on full stack problems, so I have experience all over the place. I really enjoy a good challenge, and I won't stop until I've prevailed. In my free time I've been working on a few different side projects. Some of these projects include: a clock radio (written in React with GraphQL and a node backend) running on a Raspberry Pi; a traditional music box that can take a series of notes via an Arduino; an automated grow system which uses a network of Arduinos hooked up to a Raspberry Pi brain; a particulate matter analyzer; a personal electrostatic precipitator.
