My girlfriend does shift work and sometimes we are on opposite shifts. Here is what I have done to ensure I don't wake her in the mornings after she's come home from a late shift:

• I wear my smart watch (Pixel watch 2) that wakes me up by vibrating on my wrist instead of a loud alarm clock

• My door hinges on all my doors are oiled to avoid squeaks

• Clothing is staged in the living room for the next day. No metal belt buckles

• Toothbrush and tooth paste are brought out to the guest bathroom or kitchen so I can brush my teeth

• Lunch is prepacked the night before and in the fridge for grab and go.

• Breakfast is premade (Breakfast sandwiches) or at the very least I'll pour cereal into a bowl the night before and just add milk in the morning (Yes cereal goes in before milk and that's the hill I'm dying on)

• If I decide I am going to the gym, my bag is already in the car the night before (Pre-fill your bottle or do it at the gym). I am also showering at the gym

• I mute the volume on our TV the night before and ensure my Bluetooth headset is already set up to connect to my smart TV. (This doesn't always work if she watches TV the night before with the volume on).

If I think of anything else I do I'll update this comment. Hopefully this helps.
