For the season 4, I served as AD Floor runner. Handling cast, producers, directors and DoP's. My tasks would spread when I was needed to communicate between VFX departments an AD's. When on splinter unit, was given the position of 3rd AD. First big budget set, extremely big learning curve, great crew, amazing locations! 
Season 5 I was main Props on set runner. Got to work with great department, handling daily routine. Crew was extremely prepared, so I had a lot to learn. Great experience.
