Hello Hossein,
I am excited to propose my services for developing a robust Android VPN application that meets your requirements. With expertise in Android development, PHP, Java, and mobile app architecture, I am confident in delivering a high-quality product that includes support for V2Ray, WireGuard, and OpenVPN protocols.
The application will feature a modern user interface with both light and dark modes, an interactive map for server selection, and an in-app payment system for premium subscriptions. I will ensure smooth integration for ad networks and push notifications, along with a comprehensive admin panel for server management. Your example UI/UX designs are an excellent reference point, and I will strive to create an engaging user experience.
In terms of timeline, I estimate the project will take approximately 30 days to complete, allowing for thorough testing and configuration of the servers you will provide. For the project cost, I propose a bid of 600 USD, which reflects the complexity and required features.
Could you clarify if you have any specific design preferences beyond the example links provided?
Thanks,
Kausar
