What I'm looking for

I’m looking for a role where I can build reliable data pipelines, clean and analyze large datasets, and deliver clear dashboards with Power BI/Looker Studio—while growing my cloud and ML skills in a team that values data quality.

I’m a Junior Data Analyst, currently in training at EBAC, building a strong foundation through my degree in Systems Analysis and Development. I focus on analyzing, treating, and extracting data, then turning it into insights people can actually use.

In my experience as a Multinational Solutions Analyst at Capgemini, I supported backoffice projects using Microsoft Office tools and contributed to process optimization. I also supported cloud environment creation and maintenance, working with Microsoft Azure and AWS concepts and completing introductory certifications, while maintaining data quality and integrity in day-to-day operations.

My projects deepen my end-to-end data mindset: I’ve built data visualization and aggregation pipelines (ETL) using Python and libraries like Pandas, then delivered dashboards in Power BI and Looker Studio. I’m comfortable working with large volumes of information, identifying patterns and trends, and applying Machine Learning techniques such as Linear Regression and PCA when it adds real decision value.
