The Alumni Hungary portal is for setting up and maintaining contact with full-time and part-time foreign students graduated from any Hungarian higher education institutions. By designing and developing this online application, our goal is to strengthen professional, scientific, economic and diplomatic relations with them. The sponsor of the project is Tempus Public Foundation.URL: https://alumninetworkhungary.hu

The project was implemented jointly with Navitasoft. The backend has been built on Drupal, which can secure and stable data management even for large amounts of data and provides customizability and flexible programming. We used MySQL and PostgreSQL databases, and the frontend application was written in Vue.js.We have developed several API interfaces to the portal, providing automated data delivery to stakeholders. In addition to usability, the new Baltic Transparency Dashboard will provide a reliable and up-to-date data service and a visually appealing user experience.We created the operational background with a complex virtualization solution, and the page load was reduced to less than 1 s for hundreds of concurrent users. The Drupal 9 system proved an excellent integration platform; we could efficiently serve highly complex processes.
