Mobile App Development

I am looking to build a Hybrid mobile app and require design assistance. I need help designing the look and feel of the app, as well as the user experience. The app will be made available to users for free. The app must be compatible with both Android and iOS systems and include features like push notifications, location- based services, access to device hardware or sensors, integration third-party APIs. I am looking for a developer who is experienced in creating Hybrid mobile apps and must demonstrate similar work prior to starting the project. If you believe you have the skills and experience to build an app of this nature, I would love to hear from you.
