Qwiggo

https://www.qwiggo.com/
Qwiggo is a highly integrated and feature-rich eCommerce platform.

The client had a particular requirement that they needed an eCommerce platform that would allow them to market their products using the D2C channel with minimal manual intervention.

I designed and developed Qwiggo entirely from scratch to cater to the requirement. The database and project architecture was designed keeping in mind that as many steps as possible would be automated to create an order fulfillment pipeline that would allow the client to process and deliver their products as quickly as possible.

Various external services were integrated to deliver automated notifications, updates, and information to clients and to keep track of packages during delivery.

Various data providers were also integrated using REST APIs to inform customers about the benefits they received by shopping on Qwiggo and the rewards they can redeem.
