Calling the binary from the other user profile directly should work:

  /var/guix/profiles/per-user/rodrigo/current-guix/bin/guix build SOMEPACKAGE

Or alternately looking at the store item that that user's profile points
to and using it even more directly:

 ls -l /var/guix/profiles/per-user/rodrigo/current-guix

 /gnu/store/.../bin/guix build SOMEPACKAGE

You might be able to manually register that same store item as your
user's "current-guix" profile too by symlinking the correct
things... though I am less sure of how to do that correctly off the top
of my head.
