# Description
⚡ The Challenge
- Architect and launch a high-performing online store from scratch (UI/UX, integrations, production deployment);
- Ensure rapid catalog navigation across a highly nested, multi-level directory tree;
- Automate inventory tracking, dynamic price corrections, and stock balance synchronization with 1C:Enterprise ERP;
- Integrate localized payment gateways and BNPL (Buy Now Pay Later) installment plans for the Belarus market;
🔌 Integrations
- CS-Cart — deployed the core engine, designed a custom lightweight storefront theme, and adjusted core parameters for e-com best practices;
- 1C:Enterprise — engineered a custom database synchronization bridge for catalog structures, pricing matrices, and live warehouse inventory balances;
- ERIP / Webpay / bePaid — connected localized merchant accounts for secure end-to-end online transaction processing;
- Installment Payment Cards — programmed a custom client-side financial calculator (Halva, Halva MIX, Karta Pokupok) embedded within product listings and checkout loops.
🎯 Results
- Successfully launched the platform from scratch, shifting it into the brand's primary revenue generation track;
- Achieved complete operational automation: product and pricing changes are managed exclusively within the 1C interface;
- Native integration of BNPL payment choices directly into product sheets elevated the store's average order value (AOV) by 35%;
- Engineered category and faceted navigation matrices capable of processing intense traffic spikes without degrading TTFB metrics;
🛠 Technical Challenges
- Automating Bulk Catalog Import and Multi-Supplier Feed Sync: Designing a reliable pipeline to parse diverse incoming vendor pricing sheets without exhausting memory limitations or triggering out-of-stock data errors.
Solution: Programmed a stream-parsed data processor (PHP/Cron) that reads and sanitizes raw CSV/XML supplier feeds line by line. The engine automatically maps taxonomies, normalizes custom naming variables, and adjusts pricing formulas dynamically, bypassing RAM bottlenecks and eliminating manual content management workflows.
- Robust Integration Gateway with Bitrix24 CRM: Building a persistent synchronization pipe to stream customer metadata, order details, and receipt updates from the transactional DB into the corporate CRM nodes.
Solution: Formulated an isolated REST API adapter on the backend with integrated fault-tolerant logic. Designed strict custom property maps to translate unique asset configurations into CRM pipelines and implemented an automated queue retry mechanic with exponential backoff to counter temporary Bitrix24 downtime.
- Optimizing Heavy Faceted Filtering and Multi-Attribute Data Storage in CS-Cart: Handling nested product specifications (brands, pickup types, fretboard materials, key quantities) resulted in massive index footprints and slow relational SQL joins.
Solution: Redesigned the data layer schema and deployed comprehensive composite table indexes across product feature tables. Combined with aggressive query caching policies and optimal Nginx reverse-proxy routes, this brought category view rendering latencies down significantly under concurrent user search traffic.
