Hello, How are you doing today?!
I saw that you want to build a real-time stock chart,I have been developing mobile apps since 8 years on both Android and iPhone by connecting backend panel using the Restful API.
Develop dashboard with the management control over the modules we developed as per your project scope within reasonable amount of time line and high quality assured.
I look forward to working together and create wonderful App.
