Projects

ERP For Valomarket

Developer

This site allows company employees to see orders, change their status, select distributors, etc. The Valo ERP is designed to help manage data from marketplaces and distributors, and to fulfil marketplace orders. Denis worked on both frontend and backend. The backend was written in Python using the Django framework. The project used a pre-existing MySQL database, which was provided by the client. The project uses a JWT token to handle authorization. The server API includes the ability to retrieve and edit products, orders, distributors, and marketplace related data from the database. There is also a shipment related API, which communicates with EasyPost, allowing users to retrieve shipping rates, to buy and refund shipments, and to format and retrieve ZPL encoded labels. The backend also contains an Admin page.

The system was also required to facilitate the marking properties for sale as well as the ability for users to set the status of their work on a current building project. Denis used sockets for real-time messages and he carried out performance optimization due to it having a huge DB (more than 6 million records for New York alone).
