As the founder and lead developer of OTUSONE, I strongly believe we are the ideal team for your Flutter SDK project. We have over 5 years of experience in mobile app development, specializing in Android and iOS platforms, which will be crucial to ensure seamless integration of your payment gateway across both operating systems. Our expertise in utilizing SDKs would also prove valuable as we design yours to work exceptionally well on Flutter.
The fact that the specific payment gateway has not been finalized yet won't hinder us but rather present us with an exciting challenge. Having tackled various complex integrations before, including payment gateways such as Stripe, PayPal, and Braintree, our ability to work with incomplete requirements and propose viable solutions will undoubtedly come into play.
Lastly, given our strong emphasis on quality and reliability, you can expect a fully functional and highly robust SDK by project completion. At OTUSONE, we focus on ensuring every solution created is scalable and easily upgradable – key qualities your SDK needs to have. By entrusting us with your project, you're choosing a team that is organized, collaborative, resourceful, hardworking as well as self-motivated. Let's collaborate to build an SDK that will exceed all your expectations!
