App development

I'm looking for a talented developer to create an app that is compatible with both iOS and Android platforms. I have a few specific features in mind, as well as some ideas for the general scope of the project. Additionally, I'm unsure if I need the app to be compatible with any external devices. Whoever takes on this project needs to have experience in building applications for both iOS and Android, as well as knowledge of potential third-party software integrations. If you think you can handle this project, I'd love to get your feedback.
