About Me
Hi! I'm Edwin, a CS graduate from Rutgers University.
I enjoy creating products and experiences that impact, using programming as a means to an end.
Outside of software engineering I have a variety of interests including cooking, eating, working out, guitar, music, skiing, poker, and soccer. :)
