Industrial Tender Platform: 50% Faster Procurement Cycles

An industrial machinery dealer needed to facilitate tender-based procurement for high-value equipment. I built a custom plugin that transforms Shopware checkout into a bidding interface with status-driven digital tender workflow (Submitted, Under Review, Approval Pending, Approved, Order Placed), customer tender dashboard with multi-checkout for bulk order placement of multiple approved bids, multi-level approval workflow with configurable routing rules, and Vue.js admin tender management dashboard. Onboarded 24+ enterprise customers and cut tender cycle time in half from 6 weeks to 3 weeks.

Shopware B2B RFQ Platform: 24/7 Self-Service Quotes

An industrial parts distributor needed a modern e-commerce platform to handle B2B procurement complexities. I developed a comprehensive Shopware 6 solution with two integrated components: a full-featured Request for Quote plugin enabling multi-item quotes with product search, manual entries for custom parts, per-item condition and urgency levels, drag-and-drop file uploads, and session persistence. The custom B2B theme displays extended product data including lifecycle status, commodity codes, export regulations, and environmental metrics. RESTful API with OAuth2 authentication enables ERP/CRM integration. The solution includes full German and English support, transforming manual email-based procurement into 24/7 self-service quote requests.

Integration & Performance

Performance

Shopware Import: 33 Hours to 3 Hours for 530K SKUs

A German e-commerce client with over 530,000 SKUs was trapped in an operational nightmare with a 33-hour product import process. I engineered a high-performance API integration with optimized batch processing (dynamic batch sizing based on payload complexity), database index strategy (composite indexes on frequently queried fields), asynchronous queue system using Symfony Messenger for parallel processing, and Redis caching layer for category mappings and attribute lookups. Reduced import time from 33 hours to 2.8 hours, enabling real-time inventory management and daily catalog refreshes.

ERP Integration

Pharmaceutical ERP Sync: 300K+ SKUs, Zero Fulfillment Errors

A pharmaceutical distributor operating a Shopware storefront faced critical challenges managing 300,000+ pharmaceutical SKUs with individual batch tracking, expiry dates, and strict regulatory compliance. I architected a sophisticated bidirectional ERP integration system with two-way synchronization (ERP updates to Shopware, Shopware orders back to ERP), pharmaceutical-specific batch and expiry tracking with automated validation, predictive expiry alerts and inventory warnings, asynchronous job queues for high-volume processing, and comprehensive audit trails for regulatory compliance. Achieved zero fulfillment errors, automated pharmaceutical compliance, and sub-2-second sync times.

Shopware Dropshipping Automation: 75% Faster, Zero Errors

A German dropshipping business struggled with manual order forwarding to suppliers, creating severe bottlenecks. I built a fully automated Shopware dropshipping fulfillment pipeline with multi-supplier routing logic that checks real-time stock levels, custom supplier portal with CSV import functionality, event-driven order processing with automated email notifications, and comprehensive error handling with monitoring dashboard. Reduced order processing time by 75% and eliminated manual errors.

Enterprise Plugin

Findologic Shopware Plugin: 100% Test Coverage, Zero Production Bugs

Took over maintenance of Findologic's Search and Navigation Plugin for Shopware when Shopware 6 was still in RC (release candidate). I rebuilt the plugin with a test-first approach, implementing comprehensive testing infrastructure achieving 100% code coverage with PHPUnit, GitHub Actions CI/CD pipeline with automated testing and releases, multi-version compatibility testing, and complete documentation and code quality standards. Progressed the plugin through multiple Shopware 6 releases from RC to version 6.4, transforming it into a production-grade enterprise solution used by major e-commerce operations.

Multi-Platform

Charity Donation System: 4 Platforms, 1 Seamless Experience

A charity organization initially needed a donation plugin for Shopware 5, then expanded to Shopware 6, Shopify, and WordPress. I built four completely separate native implementations, each leveraging its platform's best practices while delivering identical business functionality. Shopware 5 used ExtJS components and event subscribers, Shopware 6 leveraged entity definitions and DAL, Shopify used webhooks with Liquid integration and Polaris components, and WordPress used custom post types with WooCommerce integration. Despite different implementations, all four plugins provide 100% feature parity.

Shopware Migration: Zero Downtime, +28% Conversions

A small business faced end-of-life for Shopware 5 with zero tolerance for downtime or data loss. I executed a phased migration strategy with comprehensive data migration (customers, orders, products, categories while maintaining referential integrity), responsive theme redesign optimized for mobile, parallel systems running during transition, and complete functionality validation before final cutover. Achieved zero customer-facing downtime, 100% data integrity, and 28% increase in post-launch conversion rates through improved mobile optimization.
