Hello there,
How is it going in korea? I hope everything is good there.
I'm an application and game developer. I've been experienced on development environment for 5 years.
I see that you need a UI and UX design prototype for your apps. App design is the very crucial aspect before we executing the idea or the technical aspects. Because the apps design, especially UX design is the one that will determine will the apps usable or not. Even we got a brilliant idea about the apps gonna be, with the bad ux design of the apps, the apps will be useless, because it would to an unusable apps or even uncomfortable to use. There are principles as a UX designer to achieve "Usability" for our apps, and I'm responsible to achieve that to your apps.
Can you tell me more about the apps? Remember the key is good UX design for the apps. Love to know more from you ^_^
Best Regards,
