I agree with weasel, find a few exercises for upper back/shoulder and a few for hips/glutes and do 2-3 sets here and there when you have a minute.
Athlean X and Guerilla Zen are good. Move U guys have great visuals aids and go fast. Also you’ll probably have to try some things that don’t work so great in order to find some moves that help you.
Here’s a breathing/bracing drill from @MarkKO
"Try this:
Lie on the ground with your knees at 45 degrees. Pull your abs in, away from you waistline. Then hold your pee, take a big breath into your back, squeeze your glutes and push your hips up. Do three sets of 10.
Then set up in a 90/90, so feet flat on a wall and knees at 90 degrees with your back flat. Do the same process, abs in from waistline, hold your pee and breathe in then squeeze your glutes. this just just hold that squeeze for 10 seconds. Do this 10 times.
Then stretch your glutes, hips, hams, lower back and lats.
Do all three once morning and once evening."
This link is to another guy with shoulder issues. There are some moves and pictures. And a video of some neck/trap stretches.
Here’s a long one about serratus, scap tilt, rear Celts, etc.

A simple routine to get after your hip tilt could be
Clam shell x 8
Reverse clam shell x 8
Seated Psoas Raise with hold at top x 5
Glute Bridge with hold at top x 10
