I have some questions on your project.
1. Do you want to build VPN app from scratch or build app to switch existing VPN app?
2. If second one, which VPN you want to control?
I can work on your business timezone and keep good communication with you.
I will give you perfect result as you want with high satisfaction.
Let us discuss in detail via chat.
