In-App Ads Integration for Amazon & Microsoft Apps

I'm looking for a skilled developer who can help me with integrating in-app ads in both Amazon app and Microsoft game app. The ads should be of the interstitial and video types. I'm open to suggestions on how you think the integration should be done, whether that involves native, SDK, or API integration.

Key requirements include:
- Implementing Interstitial and Video Ads: You should have prior experience in integrating these types of ads in mobile applications
- Familiarity with Mintegral (Mobvista): Experience with this ad network is a plus
- Microsoft Game App Development: Prior experience working with in-app ads in Microsoft's game app is strongly preferred
- Creative Problem-Solving: I need someone who can think of the best way to implement these ads in both applications

Please share your relevant experience and approach to this project when you bid.
