Hiring app

My company is looking to hire a talented freelancer to create a job board app for us. We want an app that allows us to define our own hiring process and make it available on the web. We have a general idea of what the hiring process should look like, so the freelancer will be required to have extensive knowledge in this field of work. The app should be easy to use and understand, and must have the ability to store private data securely. The successful candidate should be able to provide references and samples of their previous work.
