User-Friendly Foreign Exchange Android App

I'm looking for a skilled app developer to create an intuitive and easily accessible Android app for foreign exchange. Key features and functionalities of the app should include:

- Currency Exchange Transactions: Users should be able to conduct transactions seamlessly within the app.

- Additional Features: The app should also incorporate a historical exchange rates feature, support for multi-currency conversion, and a system for tracking favorite currencies.

- User Authentication: The app should implement Two-Factor Authentication for secure user verification.

Ideal candidates should have a strong background in Android app development with a focus on user-friendly design. Experience in developing financial or currency-related apps would be a significant advantage. Please include examples of similar projects you've worked on in your proposal.
