Does the technowizard have even a single computer of his own to run spells on? Until he does that he's not going to be able to do any magic.

If he can get the nazi's making the gear he needs to run spells (especially the hardened ones) he can pull off all sorts of nifty stuff. But that's very advanced tech for the time period, and just building them runs into the stacking magic rule.

If he's limited to just his own spell casting on one computer, He can wreck the havoc that RPM is famous for. Reconnaissance is a powerful option. As is mind controlling Hitler to be more reasonable. You can't stop the nazi ideology, no, but you can stop (I mean slow down) the declarations of war to a reasonable level.

The dangerous part about the USSR, though, is that you can't wait forever. Stalin WILL launch an attack if given enough time.
