Hello
I can help you to fix the issue. I work with a team of web developers and sytem admins. The developers have to check it but I suppose there is an issue with database.
In area of web development our main specialization is LAMP stack of technologies (Linux, Apache, MySQL, PHP - laravel, zend, CI etc.) but we have experience with Python, Node.js, Angular, Vue.
If you are interested please send PM to start chatting
Best regards
