It is monstrous system, its code is really low quality, however it fully meets the business requirements! Documentation is in Russian so I'll describe only main components:

Based on Divio django-cms 2.4. Implemented tons of additional features for using in multisite and multilanguage conditions:

• Solved the problem of convenient changes in common contents on many websites, without any limitations in editing and altering the site-individual content. Web-sites can have different structure.
• Quick and easy site creation for new department in new country on new domain with new language by short 1day-guide. Sites can be fully customized for national needs but have some similar texts, products and documentation. Updating such content will take effect at all sites which are using it.
• Django template language for content editors.
• Draft\publish model with history and ability to revert changes.
• Dashboard for controlling content editors activities.
• Displaying a web-page content or sub-domain content depending on the user region. Creating sub-domains for regions in one click. Region can include multiple districts. User location determination by DjangoGeoIp.
• Cache invalidation
• and many more..

• Entity-Attribute-Value (EAV) product storage with django admin interface integration. Adding new attributes of different types to products and product types on the fly.
• Many price-fields with different currencies for one product in many regions for different customers. Price-fields can be dependent.
• Flexible template system for product presentation.
• Frequently changing data import from xlsx.
• and many more..

• Complex pdf generation from odt templates and product attributes.
