App development

I'm looking to have an app developed that runs on both iOS and Android using a cross-platform development approach. The app is a photo sharing app, where users can upload photos to create a digital time capsule. The app will feature a sleek user interface, allowing users to quickly and easily navigate the app to find and share photos with various groups/audiences. It should provide a secure experience and ensure that user's private photos remain private, while giving the user the ability to customize the app with various settings. We are looking for an experienced app developer that can build an app that is both reliable and visually appealing. Ideally, we're looking for someone with experience in the photo sharing app space to bring their insight and development skills to the project.
