Hello, I'm quite interested in developing this application of yours. Let me explain my experience.
I'm working in the android app development domain for 2 years and have developed apps in many domains like food industry, service-based apps, salon apps, etc.
I have been working with android especially in kotlin with the latest MVVM architecture components for 1 year. I have experience in working with firebase, AWS, Google API's, Fabric, Retrofit API Calling, etc.
I will design the new features for your app as per your choice and even if you have difficulty with the design I can suggest you the best design that will boost the UI & UX of your app. I usually test the app along with development and maintain the project plan that I will share with you in which I will divide all the tasks in different timelines so that you can get the overall idea of the time it will take for development.
I have worked on a Large scale project which is Habari that is live on play store and contains 400 + screens which is 100% made in kotlin with MVVM architecture. This whole app was made in a very challenging timeline of 3 months. Besides this, I have also developed medium scale projects using kotlin. So I have full experience of handling situations under pressure and also have been working on Kotlin since 1 year.
If you have any questions about my work, do not hesitate to ask.
