  • à la Société Générale (SG)
    Tech Lead/Senior Angular & Node/NestJs Developer
    November 2021 - May 2023 (1 year and 6 months)
    Mainframe machines are predominant at SG and are used with very old technologies that are increasingly rare on the technical market. One of the solutions to overcome this lack of resources is to implement APIs capable of communicating directly with these Mainframes for optimal use without knowledge of the languages and tools essential to this domain. My role is therefore to lead the development and maintenance of a set of APIs and a web interface. I joined SG as a Tech Lead, with the following main responsibilities:
    • Creation of APIs from scratch and web interfaces
    • Leadership of 4 back-end and front-end development teams
    • Design, estimation, and writing of technical documentation
    • Contribution to the development of new features
    • Participation in application maintenance.
    • Code reviews
    • Deployment with Jenkins
    • Ensuring code quality
    • Agile development (Scrum)
    • Interaction with the client and their needs
    • Documentation of all project parts
    • Staying updated on technology evolution.
