(January 13, 2023) - I've had the pleasure of working with Ivan for over a year on various projects for Pluto TV. He always asked such great questions and only needed minimal guidance to solve problems on his own. His dedication pushed him to solve any problem with thoughtfulness and care. Ivan is highly curious with standout integrity, and always follows projects through to completion. I highly recommend Ivan to be on any team, and would be happy to work with him again in the future.
