Hello! My name is Alex, and I would be pleased to implement a solution for your store. I would like to know what kind of software would you like to see developed? Do you need a new separate web app, or do you need integration with your already existing website?
I would design a modular web app that provides the functionality you want, including accounts for customers, balance and communications between admin an customers.
I look forward to working for you,
Alex Radu
