need to change login screen for my existing mobile app

I am looking for a skilled Android developer to make design changes to the login screen of my existing mobile app. The ideal candidate will have experience in Android app development and UI/UX design.

Specific requirements for the project include:

- Implementing design changes to the login screen
- Collaborating with me to refine my general idea for the new design
- Providing guidance and suggestions based on their expertise in UI/UX design

The project does not require any functional changes, only design changes. Therefore, proficiency in UI/UX design and Android app development is crucial. I am open to suggestions and guidance from the developer, but I do have a general idea of the design changes I would like to make.

If you are a talented Android developer with a keen eye for design and the ability to collaborate effectively, I would love to hear from you. Please provide examples of your previous work in Android app development and UI/UX design.
