As a project manager and developer, I managed the iteration of the French electricity grid traceability software, with specific responsibility for the Django backend and the Angular frontend. I worked in advanced technological environments such as GitLab, Docker, Jenkins, and Sonarqube, applying Agile approaches. I also took charge of project management, implementing an effective management methodology, steering the team organization, and managing deadlines. This internship was the subject of my 150-page research memoir. I explored all agile methodologies, onboarding optimization, project management and steering. I also addressed how the architecture of a software, metrics and analysis tools, as well as the study of various design patterns have an impact on the overall management of a project. The memoir was titled: "In the context of a company with a centralized IT department, how to meet the steering and management needs in the development of an application, in addition to the historically established process."
