Client Tunnel Application with 2FA & Web GUI

I'm in need of a robust solution that will facilitate the communication from client applications to backend servers through SSH tunneling. The solution should encompass a variety of features and configurations.

Key features of the solution:
- The system should allow for requests from various client applications (like browsers, DB clients, apps) to be sent to the client tunnel application ports.
- SSH client tunnel will then forward these requests to an SSH server, which in turn will relay the traffic to the backend server.
- A crucial part of the project is implementing a two-factor authentication for the SSH client.

The SSH server will need to come equipped with:
- A web-based GUI for admin screens.
- Configurations for roles, ports/backend IPs and ports mapping.
- Traffic monitoring and logs.

Ideal skills for this project include:
- Proficiency in SSH and tunneling techniques.
- Experience in developing secure systems with two-factor authentication.
- Skills in creating intuitive web-based GUI.
- Background in system administration and traffic monitoring.

I'm looking for a professional who can deliver this comprehensive solution with a focus on security, functionality, and ease of use.
