The subsidiary company of Hungarian National Bank and Budapest Stock Exchange asked us to develop bib-edu.hu education site based on native PHP and MySQL together with the connected Moodle virtual educational environment, CRM system, Android and iOS native mobile applications. We connected the CRM system to számlázz.hu in order to provide a fast and smooth financial support, and we executed single-sign-on (SSO) solution with more e-learning systems connected to the portal. The project ranged from logo design to development, and we have operated the site based on an own infrastructure in line with strict, banking security criteria.
