I am experienced in working with CRM and ERP systems, that are used in Russia. Here you can meet 1C system in almost every organization.
Building servers for 1C from scratch (file, terminal, SQL);
Diagnostics of bottlenecks, speeding up the work;
Backing up 1C bases;
Updates of 1C;
I will note once again specifically: I am not a 1C programmer and, accordingly, I do not edit configuration, create reports, change printed forms, etc. For this there are completely separate specialists - 1C programmers.
