Crear aplicación móvil sobre monitoreo de consumo de energía

I am looking for an experienced mobile app developer to help create an app about energy consumption monitoring for a new enterprise. The app should be developed for both iOS and Android platforms and include features such as real-time energy consumption monitoring. It should also provide consumers with the ability to track their energy consumption history, as well as tips on how to save energy. The final product should be a high-quality and well-designed app. As this is a business venture, the app must meet all necessary legal requirements. The developer should have a strong understanding of mobile app functionality and development. Anyone interested in this project should be able to provide a portfolio of completed work and references.
