App development

I am looking for a skilled app developer to create an app for both iOS and Android platforms. The app will have a detailed design that I have already created, and I need someone who can bring it to life. The main purpose of the app is productivity, so the ideal candidate should have experience in creating productivity apps.

Requirements:
- Experience in app development for both iOS and Android platforms
- Ability to bring a detailed design to life
- Experience in creating productivity apps
