Description

This is a customer loyalty system for all Samurai Kurobushi B2B customers. This system is used to reward customers who have purchased Samurai Kurobushi products. The reward is in the form of points that can be exchanged for various prizes. This system is also used to manage the prizes that can be exchanged by customers.

Actually this project was initially developed by another developer team. But, due to many problems and miscommunications, the client then declared the project was failed, and assigned me to rework the project from scratch. The pressure was high, because the client had already published the project to its B2B customers, but it failed.

After series of development and discussions with the clients. I have successfully delivered the first part of the system by February 2023 for distributing points based on their sales. It successfully calmed down the situation. Then in May 2023, the second part of the system, prize redeems, was launched, and it was a success. The client customers were busy redeeming their prizes / rewards using their points.
