Kotlin app and mongodb

I am looking for a developer to create an E-commerce app using Kotlin and mongodb. As I already have designs for the app, the ideal candidate should have experience in implementing designs and be able to bring them to life. The app should have features such as user registration and login, as well as product search and filtering. In addition, it should also include in-app purchases and payments. The candidate should be proficient in Kotlin, mongodb, and have experience in developing E-commerce apps. Good communication skills and the ability to work collaboratively are also important.
