During my tenure at Sopra Steria, I contributed to the technological advancement of urban mobility by developing traffic control applications for the Paris metro. As a Java Developer, my expertise in Java, Spring, and various messaging and data storage solutions like RabbitMQ, MongoDB, and PostgreSQL, allowed me to build robust, scalable systems. My involvement in this project showcased my ability to tackle complex problems, work collaboratively with a team, and deliver solutions that significantly improve urban transportation networks.
