For an embedded Linux product (LAN gateway), we need a secure and reactive web interface to configure LAN parameter, to see information like CPU/memory usage graphics, etc. Because the target has limitation, it's important to use Golang which is really well efficient.
In addition, it's important to have management of long task delay (like service reboot, etc) without freezing the web inferface (use of asynchronous call, ajax with JSON, etc).
The main goal of the job is firstly to create, put in place the architecture of this web interface with security in mind (login and secure API call like use of JWT). The web design isn't really important at this step and the focus must not be put on this part.
