Greetings,
I am Tushar , A young mobile and web developer who rather works for passion. With prior 3+ years experience in android development, I can serve you at the best.
I came up with project description and realised that you require a chat with call feature application.I can build up the project for you. For this project I will use Firebase Firestore database, and Firebase for management of database. I can provide you demo for this application prior you give me whole project.
With my knowledge and skills , I am sure I will prove this deal worth while to you.
Thanks and Regards
