Web interface developer in LUA for OpenWRT

We need to have some aditional web interface modules developed for OpenWRT.

The goal is to build on top of LUCI already present in OpenWRT by means of the LUA scripting language.

Currently we run an OpenWRT distribution on a custom router with a 3G cellular interface and we need to add the following web interface modules.

- 3G Interface configuration (Username/Password, APN, etc) and status display (Signal strength, IP, type of connection, etc)
- VRRP configuration - Ability to control vrrpd running on the system
- OpenVPN frontend - Ability to configure endpoints, usernames, certificates, options, etc
- Strongswan frontend - Ability to configure IPSec and L2TP endpoints.

The modules only need to interact with the system to send command line commands to control each of the mentioned components.
We will provide help in documenting all commands that need to be executed for each module.

Aditionaly, we would like to rewrite the firewall module, as the current one that exists in OpenWRT is very confusing.

Experience with CSS will be considered an asset.
