I need to provide limited access to team members to wpmu forum

Hi, I am building a wordpress multisite network and want to give access to one of my team members without sharing my username password to the WPMUDEV resources. but I want to limit him on how he can use it.. as in link which domains he can use the plugins on, disallow him to download plugins but only install plugins through dashboard etc. and ask questions here in the forum when he is getting stuck. Is there a way i can achieve that – any plugin or how can configure the API – kindly let me know.
