Hi there,
I'm a discord bot developer and I have made several shopify and social media monitor bots in the past. I'm very familiar and experienced with the discord API and environment. If you hire me I'll create the twitter monitor in python. I can also offer you a place where you can host the monitor on, since I have a server that's online 24/7. Otherwise I can guide you through setting up your own VPS/something else for you to host it on.
Hit me up with a PM if you're interested,
Gijs
