I am looking for a talented programmer who can create a cross-platform app that runs on both Android and iOS. The main purpose of the app is productivity, helping users stay organized and efficient. Key features that the app should have include: - User Accounts: allowing users to create and manage their own accounts for personalized experiences. - In-App Purchases: providing users with the option to purchase additional features or premium content within the app. - Push Notifications: enabling the app to send timely reminders and updates to users, keeping them informed and engaged. In terms of graphic design, a basic level of design is required for the app. The focus should be on functionality and usability, with simple and clean visuals that enhance the user experience. Ideal skills and experience for this job include: - Proficiency in programming languages such as Java (for Android) and Swift (for iOS). - Experience in developing cross-platform apps using frameworks such as React Native or Xamarin. - Familiarity with integrating user accounts, in-app purchases, and push notification services. - Basic graphic design skills to create a visually appealing and intuitive user interface. I am open to discussing further details and agreeing on the specifics of the project.
