Development of an Electronic Income Certificate System for managing e-earnings statements. The application provides a link between the public, NAV and financial institutions. During development, we created integration and asynchronous communication between different and network-separated systems, using a Java toolkit. We provided the customer with a modern administration interface for monitoring the processes. The project represents a unique fintech solution in Hungary.

The aim of the project is to replace the current data warehouse of BISZ Zrt. by introducing a more modern data warehouse that serves the needs more optimally and faster. The new data warehouse was designed according to the Data Vault methodology, on which a Business Layer is built, and data markets are created to serve regular and ad-hoc reports.
