Complex OpenCart development for Suborbia

Project brief

Keep a complex catalog and inventory aligned between the store and accounting system, correctly handle variants and bundles, recover incomplete orders and maintain a stable storefront.

What was delivered

• MoySklad API exchange for categories, products, variants, prices, stock and images
• bidirectional exchange of orders and order states between OpenCart and MoySklad
• bundle availability calculated from component quantities and stock
• variant stock aggregation across selected warehouses with option_stock detail
• correct product totals derived from warehouse options without interference from service options
• synchronisation of a technical category and OCFilter option links for catalog-wide search
• abandoned-cart tracking, scheduled email delivery and signed recovery links
• restoration of products with options, checkout contact details and eligible coupons, with successful-order tracking
• atomic file-cache writes, cleanup locking and interval-based removal of expired files
• refresh of synchronised image cache based on source-file modification time
• a single responsive purchase panel with current price, Dolyami and Split payment options, and gallery video support
• Nginx restrictions for automated crawling of combinatorial OCFilter URLs and long-lived static asset caching

My role

Analysed and extended the OpenCart–MoySklad integration, inventory and product logic, OCFilter, abandoned-cart module, file cache, Nginx configuration and product-page interface.

Outcome

One production system now combines accounting exchange, real variant-level warehouse stock, abandoned-cart recovery and storefront resilience. The changes extend the existing store without replacing its architecture.

Verification

• Live website
• The listed enhancements are verified by the current production patches and integration code.
