Muchnick attended Queens College, where he served as Editor-in-Chief of the campus newspaper.

[1] In 2002, while attending Benjamin N. Cardozo School of Law, Muchnick co-founded the popular creative contest site Worth1000,[2] together with Israel Derdik.

In 2007, he co-founded Aviary, a company that built an award-winning[3] multimedia application suite of creative web apps, with Israel Derdik and Michael Galpert.

In September 2011, citing stalling growth of the multimedia application suite, he shifted Aviary's business strategy to powering the photo-editing in third-party apps on web and mobile smart phones.

Seeing enormous immediate growth, he chose to focus the company exclusively around this new direction[4] and closed down Aviary's consumer-facing multimedia application suite, one year later on September 15, 2012.
