One of the leading banks in the Caribbean.
Caribbean Bank is the largest regional bank across the Dutch and English speaking Caribbean.

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fulfill the corporate vision and increase the development pace, the client turned to Computools team for a rehaul of an outdated online banking mobile application.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.
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
Business Process Mapping was performed by the client. CIBC FirstCaribbean Tech leaders decided on the updated mobile app feature set. Computools team received a detailed system requirements specification based on use cases by private and business customers. The client provided our software engineers with a list of features to be implemented in the course of the Backend development.
After internal business process modelling, the client selected Computools outstaffing team to complement the in-house IT department. New microservices were devised to update the online banking application according to the user requirements elicitation results while maintaining secure regional and international transactions and account management.
Computools team designed a step-by-step development plan to ensure the implementation of all critical features and microservices for the online banking application. The client performed the large-scale architecture planning, while our team devised the backend structure. The roadmap established by joint efforts of the in-house and outstaffing specialists ensured the timely implementation of the project.
Computools experts selected Java to update the client's mobile app. This object-oriented programming language ensures security necessary for a financial application. Platform independent multithreaded coding, high performance, and a mature ecosystem with multiple libraries and frameworks made Java a logical choice to meet the client’s requirements.
Microservice architecture enabled continuous and independent delivery and deployment of separate blocks of a single complex application. Tight block bounds supported technological variety and allowed Computools experts to implement the most efficient stack for each of the application’s features.
JAX-RS is a JSR standard that enabled Computools team to develop a RESTful web service that can be deployed by any Java application server. This approach was used for routing definition and to eliminate service class limitations.
Computools software engineers employed Microsoft SQL Server to maintain the server’s stable performance and ensure data recoverability and availability. This relational database management system is easily scalable, high performance, secure, and low maintenance which meets the requirements of the client’s application.
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.
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.
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.
Sprint-planning sessions and daily scrums ensured continuous delivery through transparent task distribution and assignment. For every Jira task, Computools engineers created a new Git branch. Dev branches received pull requests upon new developments’ push. After Team Lead performed code review, the branch was merged and tested by QA engineers. Jenkins continuous integration tool helped complete the build process.
