About client

Our esteemed client, Mazovian Railways, stands as one of the largest and busiest railway carriers. From 2018 to 2022, we diligently maintained their existing infrastructure, and in October 2022, a brand-new system was launched. Our partnership spans nearly a decade, collaborating on various projects throughout this time.

Business challenge

The challenge was to ensure the website’s continuous availability while promptly updating data to align with customer changes. Meeting the demand meant making the service work efficiently, even during high traffic periods, repairs, failures, and train delays. Infrastructure maintenance involved creating more than standard backups in two distinct locations.

Team composition

  • Full-stack Developer
  • Graphic Designer
  • Front-end Developer
  • DevOps Specialist
  • Infrastructure Administrator
  • Project Manager

Our solution

To ensure round-the-clock performance, we implemented a load balancer and a high-availability cluster (HA). Data was safeguarded with distributed backups. Furthermore, a dedicated email address was set up for the client to streamline the reporting process, ensuring swift responses according to the client’s expectations. Continuous monitoring of the entire infrastructure and its availability was established.
