Experience

    Responsible for analyzing, diagnosing, and solving data discrepancies during collection by various analytics tools (Contentsquare, Google Analytics, Adobe Analytics...). Also designed tools to facilitate this process for technical support for 2 years.

  • Wynd

    LOGISTICS AND SUPPLY CHAIN
    July 2020 - February 2021 (7 months)

    After a little over a year and a half at Wynd as Lead Chapter ETL, I changed teams to join the RUN (production department) and specifically the teams responsible for TMA (Third-Party Maintenance).

    New responsibilities were added with this evolution:
    - Scope and execute new product integration projects, both on the API and Front E-Commerce (Magento) side, as well as integration with the client's SI (ETL).
    - Participate in the diagnosis and correction of production bugs across the entire technical stack of projects (API, Front E-Commerce, ETL).
    I continue to be the Streamsets (ETL) referent.

  • Wynd
    Head of Chapter ETL
    LOGISTICS AND SUPPLY CHAIN
    March 2019 - July 2020 (1 year and 4 months)
    Paris, France
    I am responsible for the Streamsets software (an open-source ETL). My mission includes:
    - Defining and disseminating best and worst practices.
    - Assisting teams in the design, usage, deployment, and improvement of integration flows, both within our product and in client projects.
    - Industrializing the way of working with Streamsets within the company.
    This experience has been the most enriching I've had, both personally and technically.
