One of the features of the portal is the streamlined work process of the editorial staff and lots of convenient tools for working with content in the administrative panel of the portal.
The portals provide access to public services in public health and education 24/7. One of the main challenges was the high load on the portal servers with more than 500,000 daily visitors. For instance, in Q4 2017 we had 99.99% uptime. At the same time, the number of support calls related to technical problems was just 1-2 per week (before we began the work on the upgrade, it was higher - about 10-15 calls a week).
We used PHP + MySQL for the work. Web UI was implemented in HTML5 / CSS3. Both portals work on Drupal CMS.
SMB solutions was the segment we started delivering our projects and those we are still often engaged. To date, we have created and developed dozens of solutions for small and medium-sized businesses.
The product advances for many years and is quite popular among the users.
We use the following components:
CMS/CMF: Yii2, Bitrix, MODX, Umi CMS, NetCat etc.
Databases: MySQL, MS SQL, PostgreSQL.
