"The most devoted participant"

I have known this guy for a long time, and I am delighted with his work on projects. When he starts working with a project, it feels like he is ready to sell his soul but make it more popular! He can create 10 posts a day and I called him a content machine!!! Few people are ready to devote so much time to projects. And how he conducts events in the community?!?! Every day and it seems to me he even does not rest. I recommend him as a top participant.
