Regional Banks

Business size:



After the implementation of Computools's solution, the Caribbean Bank successfully increased performance rates by 12% while reaching a younger audience, thereby expanding the number of their users.

Working side-by-side with the client’s IT department, the Computools team implemented critical upgrades to the outdated online banking mobile application and implemented three VISA API-integrated microservices. Card processes are a core component of the bank's entire business. The client has received an implemented fund exchange interface due to our cooperation. With our solutions:

  • The organization avoided paperwork;
  • It became attractive in terms of marketing;
  • It increased customer loyalty;
  • The effectiveness of corporate culture has improved;
  • The development approach has been updated.



  • Insufficient time for internal IT department scaling
  • Unavailability of sufficiently experienced in-house engineers
  • Demanding development schedule


  • Market leader with strong demand across the Caribbean
  • Full range of financial services tailored to regional markets
  • Customer-centric business processes for increased satisfaction rate
  • Culture of corporate social responsibility and contributions to important local causes


Caribbean Bank is the largest regional bank across the Dutch and English speaking Caribbean. It offers a full range of financial services in Retail, Corporate, and Investment Banking, as well as Wealth Management and Credit Financing. With millions of private and business customers across 17 Caribbean countries, Caribbean Bank puts client at the center of business processes to ensure satisfying experience and become the first choice of financial services provider in the region.

To fulfill the corporate vision and increase the development pace, the client turned to Computools team for a rehaul of an outdated online banking mobile application. Upon analyzing the client’s requirements, Computools selected experienced software engineers to assist the in-house IT department with updating the mobile app features, developing new microservices and integrating them with VISA API.

Digital Platform & Technology

Communication Framework

Open and efficient two-way communication is crucial to the success of a digital transformation project. Following consultation with the client, we agreed upon a clear and unambiguous communication framework with scheduled regular face-to-face and online meetings and regular reports by email.Our communication ecosystem also incorporated a structured documents environment and client access to Computools' internal task managing platform. This made both the general project roadmap as well as specific processes transparent and clear for all parties.


To complement the client’s in-house team, Computools screened the pool of software engineers. The most experienced developers with Backend Java and Microservices architecture expertise were chosen to accelerate the mobile app development.


The efficiency of the Computools team is contingent on an established development flow and seamless communication between in-house engineers and the client-side specialists. A routine of regular planning sessions and review meetings promotes successful cooperation among the distributed team members.

Sprint Retrospective

Retrospectives rounded up every sprint. Development team members analyzed the strongest and weakest aspects of their processes. Each session was concluded by a plan of operational improvements to be implemented in the course of the following sprint.

Planning Session

Beside initial planning meeting, the Computools team assembled at the beginning of sprints to discuss the features to be implemented, decompose large tasks, assess and assign them to individual developers. Regular planning sessions enabled the team to keep to the development schedule and deliver the product within the deadline set by the client.

Sprint Demo

To ensure cohesive development efforts, Team Lead finalized every sprint with a review and demo session. The whole team could assess the implemented features and the overall progress of the project as well as identify future sprint priorities.

Internal Communication Flow

Computools engineers complemented an international development team that ensured timely implementation of the updated mobile application. Team members used Email, Slack, and Skype for daily communication. The client introduced technical requirements through Confluence, while Jira was the chosen task tracking tool that ensured each assignment was completed on time.

Project Management Methodology

To manage a globally distributed international team, the Scrum agile framework was implemented. Sprint-based project management methodology with daily scrums allowed the team to follow the development plan and stay flexible in the face of unexpected roadblocks. Client-side Scrum Master provided access to Jira and used it to distribute the roles, manage resources, and track the tasks. This cohesive approach enabled the team to successfully address the challenges of the project.

The design team had the task of designing a dashboard interface that would be concise, easy to understand for port staff, and without distracting elements. At the same time, however, the design had to include all the essential operational elements. The focus was on achieving that; the work was carried out dynamically, with ongoing communication with the client, taking into account all individual features of the project.
