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.

    I'm a sole frontend developer working on a "site builder" like application. ​ At the moment, users can create "sites" and host them on a subdomain "*." (All subdomains are stored on a Postgres database with a Graphql backend). The app is hosted on Vercel and is linked to a wildcard domain. The subdomain is then parsed from the host on the frontend and used for requests. Now I'd like users to add their own purchased domains to my site, but I have no idea how to go about this. So I need someone to help me set this up, and ensure that the domains are secured with SSL. I also realize that Vercel most likely can't support my use case, so I'd also need guidance in finding a tech stack that fits my needs.
