Hi! I'm Eric. I currently work as a software engineer in New York City and I have extensive experience working as a teacher, instructing people in a variety of different subjects. I changed my career from teaching to software engineering because of the excitement it brings me and the passion that I have for it. I am lucky enough now to have the opportunity to combine both of these passions - software engineering and teaching!
