The Project
Lekker Code, a leading software development and consulting firm, embarked on a collaboration with W&W AG to spearhead digital transformation within the composite insurance sector. The project aimed to enhance W&W AG's backend systems and frontend interfaces by deploying a seasoned Software Architect proficient in Java. This partnership was driven by Lekker Code's commitment to introducing cutting-edge technologies and refining processes to elevate W&W AG's digital capabilities.
The Challenges
Navigating the complexities of composite insurance demanded meticulous planning and execution. The primary challenges included architecting robust and scalable solutions in a Java-based environment, ensuring seamless integration between Angular frontends and Java backends, and streamlining business processes using Camunda's BPMN engine. Additionally, implementing decoupled communication patterns, efficient data exchange through RESTful APIs, and dynamic form handling with Pega presented intricate technical hurdles. The project also focused on real-time application monitoring, comprehensive system monitoring, and handling out-of-order events to ensure data consistency and system reliability.
The Result
The collaborative efforts between Lekker Code and W&W AG culminated in a modernized, efficient, and resilient composite insurance system. By leveraging advanced technologies like Java, Angular, Camunda, and Pega, combined with architectural best practices and monitoring tools such as Instana, Checkmk, and OpenDistro, W&W AG is now well-positioned for sustained growth and digital transformation. The successful implementation of these innovations has not only elevated W&W AG's digital capabilities but has also reinforced its commitment to delivering exceptional value to its clients in the ever-evolving landscape of composite insurance.
