Building a custom commerce platform for a growing retailer

The Challenge

A fast-growing direct-to-consumer retail brand was hitting the architectural ceiling of its off-the-shelf monolithic e-commerce software. Peak flash sales triggered frequent checkout timeouts, inventory sync delays across channels, and page load degradation that directly hurt conversion rates. The merchant needed a high-performance commerce foundation capable of handling rapid catalog growth and surge traffic without locking them into rigid template restrictions.

The Approach

DevsTek engineered a modular, headless commerce architecture separating the customer-facing frontend from backend ERP, PIM, and fulfillment integrations. By leveraging event-driven microservices, real-time inventory management, and optimized CDN caching, the new platform ensured sub-second page loads globally. The solution also included automated cart recovery and dynamic personalizations tailored for high-volume promotional events.

The Results

• Zero downtime during major peak sale events with a 3.5x increase in concurrent traffic handling
• Page load speeds improved by 65%, boosting mobile conversion rate significantly
• Automated multi-channel inventory synchronization eliminated overselling incidents
