Well, I know Discord, have been using it for a long time due to gaming purposes mostly.
Now, let's come to the work, I have the experience of making Discord bots that make almost everything possible. Till date, I have made bots that relay the in-game chat from a game server on to a particular channel in discord and also sends the message on that channel from a particular role back to the game server in-game chat; and more such things.
Moreover, I believe with the discord API, everything is possible. And yeah, I also have experience in working behind websites and stuff, so, I don't think that the front end will be a problem.
I would like to listen more to what type of work it is. The number of days needed will vary as per the demands of work. That is why I need more information to be more accurate on when I can deliver it.
