Is it possible to make a resume on my ipad

Some may be, some not. It would be up to the developer of each individual app to make both an iOS version and a windows version, so one file could be edited on either platform. E.g. Microsoft does make an iOS version of their Office apps and so an MS office file can be edited on iOS, Windows, OS X or Android (although, iOS Office apps are free while their full featured windows and OS X versions are not).

Check out Pages: Pages on the App Store.

Sure, there are dozens of writing and word processing apps you could use to make one. New iOS devices get Pages for free, and MS Word is free to download from the App store as well.

There are even specific resume builder apps available as well.

are they all compatible with windows?
