  • Pernod Ricard
    Data Scientist
    AGRICULTURE
    March 2024 - September 2024 (5 months)
    Paris, France
    At Pernod Ricard, my experience as a Data Scientist has been profoundly impactful and technically enriching. Python served as the backbone of my operations, where I utilized most of the key libraries for Data Science. I ensured code industrialization through best practices in version control, unit testing, and continuous integration, which facilitated seamless model deployment and maintained robust, scalable, and maintainable code.

    SQL proficiency was essential for extracting, manipulating, and analyzing large datasets stored in relational databases. Writing efficient SQL queries allowed me to streamline data processing and ensure the accuracy of data feeding into my models.

    Azure DevOps played a crucial role in enhancing collaboration. I used it for version control, CI/CD, and project tracking, ensuring a smooth and agile development process.

    Working in a collaborative environment, I engaged with cross-functional teams, translating complex data insights into actionable recommendations that drove tangible business outcomes.
