You should definitely mention how tenuous Poland's grasp on its non-Polish territories, especially the Ukraine. That's the only glaring thing about the later part of the app for me. One thing you could do to help yourself out is make more out of the dissonance between the government and the industry, but that will depend on what you are wanting to rp.

The early part of the app isn't ideal, however. I think the way you describe the rise of Poland needs work. For one, tech isn't the field that an economy starts with. Tech means education, and education means a functioning middle class. One thing you could pose Poland as in the thirties and forties is a place that Russia bought from because they were cheap that way. Polish machinists make replacement parts for Russia and the Ottoman Empire. They rebuild their military through a universal draft where draftees are divided between military service and public. From their, they are able to form the middle class necessary for a bureaucracy.
