ArgentinaWhat I'm looking for
I'm a Systems Analyst and Economics student with over a year of experience as a Junior Data Analyst at an IT company. I specialize in transforming raw data into analytics-ready datasets and actionable visualizations.
At Compuaccess, I performed ETL tasks, supported SQL-based data extraction, and prepared clean datasets used in Power BI and Excel for reporting and analysis. My work contributed to a 13% annual reduction in operational costs and supported 15.7% savings in supplier-related expenses.
I'm self-taught in Python and SQL, and I've completed certifications in Data Analytics and Tableau, which complement my hands-on experience with data modeling, warehousing, and ETL processes. I emphasize continuous improvement, discipline, and rapid learning.
I'm seeking opportunities where I can apply my technical skills and analytical thinking to drive data-informed decisions and measurable impact for an organization.
