Digital Java Transformation for an Automotive Company
Interval supported a global automotive brand in enhancing its vehicle planning and production platform - modernising core Java components and preparing the system for cloud migration. The result: faster performance, improved maintainability, and a foundation for long-term scalability.
Situation
A multinational manufacturer of luxury vehicles and motorcycles operates a digital platform that manages planning, ordering, production and distribution of vehicles. This platform integrates multiple departments - Sales, Purchasing, Production, Financing and Distribution - across the organisation to ensure that orders are fulfilled efficiently, while accounting for capacity and operational constraints at every stage of the manufacturing process.
The platform, originally developed in 2015 as a Java Enterprise Edition monolith, had served the business well. However, with the continued evolution of the automotive industry, the company recognised the need to both enhance functionality and ensure the system remained well maintained.
In the short term, the company partnered with Deloitte to deliver new business-focused features and provide ongoing support for the monolith application. In the mid-term, the goal was to refactor the platform into microservices and migrate to the cloud for greater flexibility and scalability.
Approach
Interval deployed a dedicated Java Developer to support this transformation. Responsibilities included:
Designing and implementing user stories in both frontend and backend components
Reducing web page load times to under one second by optimising JPA/SQL queries and improving REST service response times
Performing detailed code analysis to identify logical components within the monolith and refactor these into standalone microservices
Investigating and resolving production incidents and end-user issues
Collaborating closely with the Product Owner, Business Analyst and other stakeholders to shape new features
Documenting all work - feature preparation, technical design and implementation - on Jira and Confluence
The developer’s efforts laid the groundwork for strategic system modernisation while meeting immediate business needs.
Outcomes
The first project phase was delivered within six months, ahead of schedule and within budget. A subsequent phase commenced shortly thereafter.
All business goals of the initial engagement were met, enabling the organisation to continue offering high-performing digital services to customers.
Technologies used included: Java 11, Java EE 8, GlassFish, Kafka, Angular, Maven, Docker, AWS, Bitbucket, Sonar, and IntelliJ IDEA.
The proposed transformation - from monolith to microservices - was approved by leadership and is now in progress. The overall programme is expected to span several years, delivering substantial improvements in efficiency, process agility, and system security.
