Our Expertise

Exotics Racing: Custom ERP

We rebuilt and improved a custom ERP to automate the processes of the world’s largest supercar fleet company. We re-organized the architecture and migrated data to the AWS cloud, developed new features: customer management, human resources management, finance management, inventory management, and fleet management.


This was an existing project that had been developed by several teams in the past. The technologies were outdated. We made legacy code refactoring, created a new CRM, established a multi-layer security system, and switched to a new search engine. This allowed us to improve website performance, streamline the development of new features, and improve security.
