vpn app with custom sni and payload

I need an experienced developer to create a VPN application for me. The app must be created for Android and should include a custom SNI (Server Name Indication) and custom payload or additional parameters. The developer must have experience in mobile app development and have an understanding of custom SNIs and payloads. I'm looking for a clean, user-friendly design and a reliable and secure VPN implementation that would provide maximum privacy and security. If you have the experience and skills necessary to complete this project, I'd love to hear from you. Thank you!
