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fulfill the corporate vision and increase the development pace, the client turned to Computools team for a rehaul of an outdated online banking mobile application.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.
Working side-by-side with the client’s IT department, Computools team implemented critical upgrades to the outdated online banking mobile application and implemented three VISA API-integrated microservices. As a result of efficient collaboration, the goals and objectives were achieved, the client is completely satisfied with the finished mobile application, which opens up new opportunities for its consumers.
Several key options we solved:
Provide users with ultimate transaction control, security hold, and parental control options.
Implement transaction validation when the account holder is abroad.
Implement service that allows users to create, preview, edit, and stop transactions.
Business Process Automation
Digital Platform & Technology
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.
Microsoft SQL Server
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.
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.
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.
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.
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.
