Same Side Navigation for bigger and smaller screens?

I am trying to find a way to navigate amongst rather complex content using an "admin" side navigation. The goal have been to use same navigation regardless of mobile or desktop.

Am I thinking in the right direction or do I have to reconsider?

Using Hamburger

Bigger screens: The menu should open and close at same level as content. 
Smaller screens: The menu should open and close above content

Resize Windows

Bigger screens: Full menu as default
Smaller screens: No menu as default

Using menu buttons (Home etc)

Bigger screens: Select the active link and stay open
Smaller screens: Select the active link and close

At reloading page

Bigger screens: The menu level select persists and active links should be selected
Smaller screens: The menu should stay closed

Using link on the content

Bigger screens: The menu should stay open at current level and select active link
Smaller screens: The menu should stay closed
