Good day!

I am interested in your project in the fitness field. I have experience developing mobile applications using cross-platform technologies (React Native, Flutter), which allows simultaneous support for iOS and Android.

Since you already have an API built on .NET 8, I am ready to efficiently integrate it into the app, as well as participate in further support and feature expansion. My priorities are reliability, user-friendly interface, and meeting deadlines — an MVP within a month seems like a completely achievable goal.

I am ready for long-term cooperation if the first version is successfully launched. I would be happy to discuss the details in person.

Hello!

My name is Roman, I am a .NET developer with experience in creating cross-platform mobile applications.

I have practical experience in developing similar solutions — I built my own cross-platform (iOS/Android) startup Rooper from scratch, based on React Native and .NET.
I used a number of modern technologies, including:
- Login via Apple/Google
- Notifications through Firebase
- Integration with LiqPay for subscriptions
- Google Cloud for working with maps and locations
- Creating and integrating an AI-based assistant
- And much more

I also independently published the app on the App Store and Google Play, so I am well familiar with the full development cycle — from architecture to support in the production environment.

👉 To learn more about the project, I invite you to visit my website: www.rooper-web.com
There you can get a more detailed overview of the project’s functionality and go to the App Store or Google Play to test the application personally.

💡 In your project, I am interested in the opportunity to:
- Implement a modern mobile app based on an existing API;
- Use my experience to create a quality MVP in a short timeframe;
- Join a long-term collaboration.

I would be glad to learn more about the functionality, design, and your expectations. Ready to start work as soon as possible.

Best regards,

Good day!
My name is Oleksandr, I am a full stack developer with 4 years of commercial experience. I have experience working with both backend on .NET (specifically .NET 8) and frontend for web and mobile platforms.
I have familiarized myself with your request regarding the fitness app. Backend on .NET 8 is a familiar environment, so I can easily continue its development and support.
For the mobile application, I suggest using Swift with SwiftUI as the main technology. This will allow creating a stable, fast, and native app for iOS, with the possibility of further adaptation or expansion for Android if needed.
✅ Ready to implement the MVP within 1 month. In case of successful launch — open to long-term cooperation.
Ready to discuss technical details and next steps.
