I contract with indie teams and have helped many AAA titles with their Voice Over. From casting and pre-production to editing and integration, VO is a specialized part of a game's audio that requires a large amount of coordination and planning.

Some of the titles I have worked in the VO process on are:
Horizon Zero Dawn (Engineer)
Gears of War 4 (Editor)
Final Fantasy XV (Editor)
Octopath Traveler (working title, VO Coordinator)
Left Alive (VO Coordinator)

I've also directed and/or engineered a couple not-yet-released titles as well.
