About

My interest in data stems from a strong belief: it has the power to transform decisions into strategic opportunities. With two years of experience as a Data Analyst, I designed interactive dashboards in Power BI to optimize the performance of commercial and logistics teams. These tools helped reduce costs by 8%, improve processes by 15%, and simplify decision-making through clear and actionable visualizations. During this experience, I automated data imports using Fivetran, Excel, and Google Sheets, integrating new data into dashboards updated daily. This reduced human errors by 15% and data processing times by 20%. To strengthen my technical skills, I completed an intensive Data Analytics program at Le Wagon, where I honed my expertise in Python (pandas, matplotlib, seaborn, sklearn), SQL (BigQuery), and data visualization tools such as Looker Studio and Power BI. In the final project, titled "I Will Survive", I developed a correlation matrix and a cardiovascular health score integrated into an interactive dashboard. This project, focused on preventing cardiovascular diseases, is available on my portfolio. Today, I aim to leverage this dual expertise—operational and analytical—to help businesses fully realize the potential of their data, whether by optimizing performance or enabling data-driven decision-making through reliable and actionable insights.
