Pherum managed Vital directly
"Vital is a genuinely nice loving human being, a great person and colleague to us, a hardworking and talented resource, he never says no to any tasks being assigned or asked to help and always looking for helping his teammate as much as he could, it does not matter what time was it he was always there to help."
"Watching him walk away from my very own team is painful as a teammate, but also happy for him to grow and get higher in his career and can only be jealous of the next team he will be working with."
"Best, Pherum Un"
