Omnichannel E-commerce Platform

The client is a fashion chain with 50 physical stores needing digital transformation to catch up with online shopping trends. Czen built an e-commerce ecosystem perfectly synchronized between Online (Web/App) and Offline (POS at stores), delivering a seamless shopping experience.

Project Challenges

The hardest problem was real-time inventory synchronization to avoid overselling during Flash Sales with thousands of concurrent orders. Furthermore, the system had to withstand traffic spikes of up to 100,000 CCU.

Solutions & Results

Czen utilized a Cloud Native platform with Auto-scaling capabilities to ensure zero downtime. Multi-layer caching mechanisms (Redis) and distributed databases were applied to optimize response speed.

As a result, the client's online revenue grew by 200% in just 6 months. The system operated smoothly even on Black Friday with over 50,000 orders processed successfully.
