• During my time at RGI Group, I contributed to the development and maintenance of core systems for Société Générale and AXA. My focus was on building and enhancing complex insurance management systems and integrated business solutions that support multi-company, multi-territory, and multi-language capabilities.
• Developed a core system supporting the full insurance lifecycle, including functionalities for user management, claims processing, insurance policies, premiums, and payments. The system also integrated multi-threaded batch processing for operational efficiency. The solution is used for managing client data, claims, third-party interactions, and optimizing operational processes.
• Led the development of an integrated management system for AXA, focusing on streamlining processes for quality management, environmental management, and health and safety management. This system was tailored to meet organizational needs, ensuring alignment with best industry practices. I contributed across the software development lifecycle, from requirements gathering and design to implementation and deployment.
• Developed core system functionalities using Spring Boot and Angular.
• Integrated SOAP and REST APIs for communication between different system components.
• Worked on Camunda to automate workflows and processes for Société Générale.
• Contributed to optimizing processes using Scala and managed batch processing with single-threaded and multi-threaded batch in the Société Générale insurance system.
• Engaged in testing and deployment using TDD and BDD methodologies.
• Provided application support (Support Applicatif) by troubleshooting and resolving production issues, ensuring system stability and smooth operation.
