React.js is an efficient, declarative, and flexible open-source JavaScript library that is useful for developing user interfaces specially for single page apps. With React.js, users can build complex user interfaces from “components.” Components are small and isolated pieces of code.

React.js can also be used as a base in the building of both mobile and single-page apps. Although, complex React.js apps usually require additional libraries for interaction, routing, and state management with an API (Application programming interface).

React.js makes it possible for developers to design large web apps which can change data, without reloading the page.

    I need a developer to help me design a web asset storage mechanism to store dynamic data about a home. The assets stored range widely by asset type. DynamoDB or MongoDB seems to be the best fit because of the vastly dynamic nature of the assets we want to store. What I'm envisioning is a frontend PHP or JavaScript module that talks to a middleware API system that makes requests to the backend. Created a basic development environment based on Linux using a GitLab repository. This will be a very collaborative project and regular communication is essential as we will be building modules for the system in parallel.
