Trescal is the world leader of metrology. It’s a large group of metrology laboratories that uses Atlas, an internal ERP running to manage their global activities. I joined the dev team to maintain the existing Atlas running on old technologies (Java 8, Gradle 7.2, JSP, Rest API, Jpql, Tomcat…) and prepare the development of Atlas version 2 in more modern technologies (Java 17, Spring boot, Angular 14, Gradle, Docker…). As the software security reference, i’ve introduced and installed security practices in Atlas enhancement development cycle. Also develop the whole API integration project between ERP Atlas with Microsoft 360 CRM provided by a third party. I contributed to improve Agile scrum environment for the team. We worked in an international context with english as the main language of communication and the dev team located in different countries around the globe (USA, Germany, Morocco, France, Spain, Singapour…).
