about the project

CarTrawler's Need

As a high-growth travel software  company, CarTrawler was looking to increase engineering headcount with flex team members who specialise in Java, React, and Angular.

To achieve the desired level of flexibility in scaling, Cartrawler reached out to Zartis to set up a dedicated development team that would work as a seamless extension of their existing software teams.

The initial goal of the partnership was to provide CarTrawler with the resources they needed quickly, without compromising on quality and efficiency.

The solution

Kicking off the collaboration in August 2021, Zartis was able to quickly set up a team of 3 engineers, which has since expanded to 7 engineers.

The team consists of senior engineers, who were able to hit the ground running and deliver value quickly and consistently. Not only do they increase the speed of development at Cartrawler, but are also able to share their knowledge and expertise.

The Zartis engineers are fully integrated across multiple agile squads, supplementing the in-house teams as per the needs of the client. Our dedicated developers work in similar time zones to the CarTrawler teams, making communication smooth and easy.



On the frontend side, the Zartis engineers are able to bring in expertise across modern JavaScript and Typescript technologies, while also supporting the CarTrawler team in the transition from AngularJS to React.


On the backend side, our engineers brought expertise in Java, Docker, Jenkins, Microservices architectures, and cloud platforms such as AWS.
