Solar Power Plant App Development Project

I am looking for a developer to create an app for my solar power plant. The primary goal of the app is to monitor energy production. I prefer a cross-platform app that can be used on both iOS and Android devices. The app should have real-time monitoring capabilities and a user-friendly interface. In addition, I would like the app to have historical data analysis features. Ideal candidates should have experience in app development, as well as knowledge of solar power plants and energy monitoring.
