Hello, I'm Jiwon.
There are several improving options what I can provide more.
1. This site is made by based on own backend system
I can provide you the database scheme, SQL, or even setting up for your service.
2. Material Dashboard for Admin
You can create and edit all posts, categories, managing subscribers. If you want to look around the admin pages, just sign up here, email me for your id, then I'll give you the authority to do.
3. Specific Design Pages
Maybe the pages all looked pretty same, don't they? Since this site is a kind of prototype, I can make different design if you want.
4. And we can always talk and negotiate.
With proper and reasonable prices, I promise I'd do my best to accomplish.
