There might be some uses with ninja in their name but if you have came across some forum member with this name then it must be TryNinja as he has developer and have built some sites and keep posting good technical content on forum.

He has own website forum related information and you can check it here : Ninjastic.space - BitcoinTalk Post/Address archive + API
