Building a product management system for Magento(Incl other channels eg. shopify)

Hi Guys,
As the title says. I am currently building a system in laravel to easily manage the products.
Our company finds the Magento Catalog Management System very difficult to handle bulk products.
We will also integrate other channels like Shopify, Amazon Marketplace. It will be like All-in-one product management system.

So can you please put your thoughts on it?
Will you be interested to buy something like this.
