backend(in C++) for an inventory module

I'm in need of someone with experience in developing backend C++ programs to create an inventory module for my business. The features that I need in the module include tracking inventory levels, generating reports, and managing product categories. Additionally, I need the inventory tracking system to provide real-time tracking, as opposed to being updated on a periodic or manual basis. Lastly, my business involves tracking more than 500 products, so someone skilled in handling large scale data would be ideal.
