About Pierre

Research engineer specializing in the management and processing of large amounts of data. I design and optimize data pipelines to make complex data streams understandable through dashboards tailored to end-user needs. With 4 years of experience within the PERFANALYTICS project, I have held the roles of Full Stack Developer, Lead Engineer, and Data Engineer to analyze sports performance at an international level in collaboration with coaches and researchers.

My core skills include:
- Pipeline design (Python, Apache Airflow, Docker) for ingesting and processing performance data and videos.
- NoSQL/SQL database management (MongoDB, SQL Server) and query optimization.
- Development of ETL and analysis tools (ReactJS, interactive dashboards with Dash Plotly in Python)

    Montpellier, France
    The Perfanalytics project is a French research project linked to INSEP, aiming to support French sports federations in their pursuit of excellence at the highest level. I am currently working there as a Full Stack Engineer and Lead Engineer to develop, maintain, and sustain pipelines and dashboards that supported the various federations during the 2024 Olympic Games.
    I have developed tools for sports performance analysis from video (manual and automatic annotations), provided data ingestion pipelines for official results and videos to facilitate processing, and created dashboards developed with coaches to provide them with precise feedback that meets their needs.
    Finally, these tools have been industrialized and are integrated into INSEP's Sport Data Hub (SDH) to maintain their availability and maintainability after the project's end.
