My company is in the fintech space and we have a prototype that is used by our sales team. We have 2 challenges related to internationalization:
1. Making it easy to create translated versions of the demo (we have this partially solved using variables).
2. Easily changing the 100s of numbers that appear across the demo based on different interest rates and currency exchanges. This would be done using Axure's math functions.
There is almost no design work involved in this project, it's mainly a programming project, so that should be your main strength. Having a good intuition with numbers is also a plus.
