Hello, thanks for sharing your project,
I have an experience in Android development using modern tools and best development techniques to deliver the project on-time. I write maintanable code that encourages readability.
For such an app, there might be a need to use web views/open in browser facility, but I'll need some more information regarding the exact functionality of the app from you.
I assume you will use APIs to make the "book/reserve" click on the target site, but you can let me know what exactly the flow of the app should be and we can discuss how to implement it seamlessly. I can also integrate the login from the app to your target URL.
Any further details can be communicated with me and I'll be happy to use your feedback to develop the app. I will be happy to discuss any modifications you want regarding the architecture/style of the app with you.
