Odolný a škálovatelný backend pro elektronický obchod

About the Project

The client operates a large-scale e-commerce platform that faces extreme traffic fluctuations during promotional events. Maintaining uptime, reliability, and transaction safety was paramount, as even brief outages or inconsistencies could lead to significant revenue loss and reduced customer trust. The brand required a backend that could adapt dynamically to demand while ensuring an uninterrupted shopping experience.

About the Project

We architected and implemented a distributed, polyglot backend based on microservices principles. The Users & Catalog Service was developed with NestJS and PostgreSQL, leveraging Redis caching to deliver sub-100ms responses for product queries. The Order Management Service, built with Java/Kotlin and Spring Boot, handled all order lifecycles, ensuring atomic operations and data integrity through transactional guarantees. gRPC facilitated efficient communication between services, minimizing latency. RabbitMQ managed asynchronous event publishing for notifications, decoupling non-critical operations from the main transaction flow. All components were containerized using Docker, ensuring scalability, fault tolerance, and deployment consistency across environments.

Client Testimonial

“The new backend architecture transformed our e-commerce operations. Even during Black Friday, the platform ran flawlessly with no slowdowns or transactional errors. The modular design and polyglot approach not only improved performance but also gave us the flexibility to evolve each service independently without downtime.”
