Android VPN Application Development

We are looking for an experienced Android developer with expertise in developing VPN applications, specifically for integrating a SOCKS5 proxy client with Stunnel. The project involves creating a seamless VPN experience with the following requirements: Key Features: SOCKS5 Proxy Client Integration with Stunnel: When the user clicks "Connect," the app should start Stunnel and establish a connection to the SOCKS5 proxy via the Stunnel host. The app must properly handle network traffic routing without causing any loops by using split tunneling (excluding the app's own traffic from being routed through the VPN). Login System (PHP + MySQL): Users will log in via a PHP + MySQL-based backend. Multiple devices per user should not be allowed, ensuring secure and exclusive access for each account. UI/UX: A colorful, user-friendly interface. Buttons for "Connect" and "Disconnect." Display account validity and connection time information pulled from an API. Show real-time bandwidth usage and speed when connected. Requirements: Proven experience in Android development, particularly with VPN and proxy systems. Strong understanding of SOCKS5 proxy, Stunnel configuration, and split tunneling. Experience with integrating PHP + MySQL for login systems and user management. Ability to develop a visually appealing and intuitive user interface. Additional Notes: The developer will need to work closely with our API to retrieve necessary account information. If you have the required skills and experience, please apply with your portfolio or examples of similar work. We look forward to working with you!
