Business Challenge 

For developing the new portal, Tremend employed advanced technologies to solve some complex problems regarding the integration of the online Carrefour systems and the offline ones created for taking the orders and preparing them in the hypermarkets.

Solution delivered by Tremend 

Dedicated Scrum teams have designed and built the solution to integrate all the independent projects (,, and – the corporate website) under the unique portal, with two main technical components:

  • The Marketplace system – based on Magento 2 with Elasticsearch and Redis
  • The unified service – developed from scratch on top of Symfony, for cart & checkout.

Migration to GCP:

  • Provisioning & configuration management: Terraform, Ansible
  • Highly available, multi-zone deployment
  • Deployment: Kubernetes (GKE), Compute Engine, LB, CloudSQL, Memorystore
  • CI / CD: Bitbucket, Bamboo
  • Monitoring: Prometheus, NewRelic, Nagios, ELK

Performance tests ensured the solution would deliver the intended traffic requirements. Security penetration testing made sure the solution can be safely launched.

Expertise required:  eCommerce, Microservices, scalable traffic solution, Node, Magento 2, Symfony3, Angular, Angular Material, Django, Golang, UX, design, CI/CD, Automated QA, Bare Metal Cloud, Google Cloud, Rancher, Docker, Ansible, Kubernetes

The products ordered online can be delivered anywhere in the country or picked up at any Click & Collect point in the Carrefour hypermarkets. This is a first for an FMCG retailer.
