Hi, We have previous experience with real estate websites, online portals and backend agent and property management systems.
The applications are normally developed in PHP, Laravel or Code igniter.
I have seen the screenshot and the backend system you have shown.
We'll create a organized, commented and easy to manage code. Will be PHP so that it can be handled easily.
We'll use the same theme that you have provided. We'll fully customize it. For the backend we'll develop another design, or use the resources of this themes.
