What I'm looking for

I seek a collaborative role in transportation or logistics analytics to apply Power BI and Excel, drive operational insights in wholesale operations, and grow my SQL/Python skills while delivering data-driven decisions.

I am an enthusiastic data analytics student pursuing hands-on experience in transportation analytics, skilled in Power BI and Excel with a passion for solving logistics challenges.

I have supported analysis and reporting roles at Star Garments and Chic Le Frique, gathering, cleaning, and visualizing data to help companies make informed decisions and ensure organized, accurate datasets.

I built interactive dashboards tracking sell-through rates, inventory turnover, and margin performance, and prepared financial and branch performance reports during an internship at Regional Development Bank using Excel and Power BI.

My research on service quality and customer satisfaction used regression analysis in IBM SPSS, and I mentor peers in Excel and Python basics; I am eager to join a collaborative team where I can apply my analytical skills and continue expanding my SQL and Python proficiency.
