Banking and Finance

Business challenge

The beneficiary of our services wanted a tool to manage all aspects of a prepaid card for business expenses, thus enabling companies to manage corporate expenses more efficiently.

The tool is aimed at businesses that want their employees to pay for corporate expenses in an easy way and at the same time to have a detailed view and control over costs.

Team setup

We embrace Agile methodologies in most of our projects. Many times it is our customers and partners who ask us to use Agile methodologies (Scrum , Kanban) from the inception of the project. When the choice is left to our engineers, we carefully analyze the project specifics, and we propose a project management methodology based on Scrum or Kanban which best fits the specific project needs and context.

The development team consists of 6 developers based in our headquarter: 3 backend developers,1 frontend developer, 2 QA. We work closely with the Client Service Team and the Infrastructure Team including project managers, sales, marketing and design specialists.

As in all of our projects, we worked in an agile and flexible way. We had daily scrum meetings with sprints and demo release every two weeks.
