Backend code is the part of a website or application that isn’t visible to the user. The code is a behind-the-scenes part of development, requiring a high level of competency regarding coding and the server that is being used. A backend developer works on the implementation and configuration of systems, and thus provides the building blogs for a website or program.

    We're looking for either a combination of front and back end developers or a full stack developer to help get this website off the ground. We have an idea of the aesthetic that we're going for and a limited skillset to get there, so a web designer is also something we could be interested in. We're looking to include quite a few common and custom plugins/features on a gun-friendly hosting platform, some of which are obviously legal sensitive so we would need them to flow accordingly. We'd like to have the website off the ground ASAP, but realistically we're looking to have this done in 2-6 weeks. We understand this is above the average website request, and our budget reflects that! We'd love to negotiate compensation with any and all that are seriously interes...
