VPN for iOS with Custom protocol

I’m looking for an experienced iOS developer to build a secure, audit-compliant VPN for my business. The VPN should use a custom protocol that allows for robust security and privacy. Authentication should be enabled via password, and the service should comply with relevant audit requirements. It should also be secure enough for legal and compliance purposes. Furthermore, the VPN should be tested and validated for performance, scalability, and reliability. This project will require an expert in networking protocols and iOS development, as well as knowledge of security best practices. If you think you can meet these criteria, please reach out. I'm eager to begin this exciting project.
