About Lucie

Passionate about data for several years, I have oriented my career towards Business Intelligence, a field in which I thrive. My expertise has been honed around Power BI, a tool I appreciate for its ability to transform complex data into clear, reliable, and accessible analyses.

Through my experiences within various organizations (SNCF Voyageurs, Bricoman, Leroy Merlin…), I have developed an approach focused on understanding the business, data quality, and designing truly useful BI solutions. I enjoy seeing projects through to completion: structuring, analyzing, modeling, designing, and supporting users until they can operate autonomously.

Curious and constantly learning, I continuously train myself to strengthen my skills, discover new tools, and deepen my understanding of data best practices. I also aim to gradually expand into Data Engineering to better master the entire data processing chain and enhance the value of my BI projects.

My goal: to deliver accurate, clear, and precise work, while bringing positive energy and constant commitment to every mission.
