This project is a system for the automatization of price list processing by procurement specialists. The customer was a large Switzerland vine trader, and he has a lot of suppliers that provide a big amount of data about prices for vine products every day. Normally about 3 decades of procurement specialists were needed for processing all supplier's price lists, after the automatization of this process, only 2-3 specialists are enough. Moreover, the storing of all information in the relative DB makes it possible to provide a dynamic analysis of the market.

• requirements discussion with Customer BAs
• design of the general architecture of application
• DB design and optimization
• setting up and support CI/CD processes

It is a standard Enterprise Content Management (ECM) system that supports all kinds of municipalities in the Denmark for case management. It is characterized by a high degree of customization, extensibility, and scalability because each municipality has specific processes, workflows and requirements to data models and UI. Planned loading is more than 200K users and 500 operators. The backend is implemented as a set of microservices and the frontend is presented by a custom framework for forms building.

Dmytro was involved to the development of the backend and frontend for two new modules:

1. First one is for integrating the Acadre web site with a desktop application used for processing documents at several municipalities;
2. The second is for integrating documents processing workflow with the common Denmark database for monitoring citizens' request statuses.
