Job ID: 34250744

Budget: $29 – $30 USD

I'm looking for someone to add a option to set total data usage limit for individual user + option to view current usage in a Open Source Wiregaurd VPN Server Application build in NodeJS & Express.
Its a simple Web Based Wiregaurd management UI see the GitHub repo for a good idea

Currently it shows Download upload speed of connected clients and total Data usages when hovered over upload/ download icon. but it resets everytime the server is restated. I'm looking for a persistent solution. by the way, application also runs as a docker image.
