Joshua Fleitell
Josh has been taking things apart since he was a little kid. Not much has changed, except now he (mostly) puts them back together again. For Sentant, this often means constructing audio-visual equipment and server racks, as well as integrating A/V and corporate systems. Joshua is proficient at multimedia coding such as Arduino and MaxMSP, A/V suites such as Touch Designer, as well as shell scripting and systems integration. While not pushing buttons for other artists and designers, he can usually be found in the dark doing strange things with electricity; creating the things that go blink in the night. His work as a creative engineer and programmer can be seen in a variety of venues across the world, with clients ranging from Blue Man Group to the Empire State Building. He has served as technical director for the band OKGo, where he was responsible for ensuring visually-rich performances went smoothly on tour for this popular act. If you're ever been in New York City and seen the lighting on the Empire State Building or the Kosciuszko bridge, you've seen Joshua's work first hand. Joshua holds a Bachelor of Fine Arts degree from the California Institute of the Arts and worked for industry-leading multimedia firm WorldStage (formerly Scharff Weisberg) before transitioning to consulting work. https://www.linkedin.com/in/joshua-fleitell-4698676/
