You will need to help me develop a Java backend engine
1) It will be based on Dropwizard framework to have a RESTFUL service returning JSON (http://dropwizard.codahale.com/). The build will be done via ANT.
2) The service will be responsible for executing (on a schedule) specific commands to run a security scan on the website. These commands could either be specific classes or invokations of command-line programs.
There will probably be a database component where you will store info about the users. I will give you some skeleton code which you will have to extend (or you may start from scratch). I will guide you in the architecture project implementation overall.
