I’m looking for a Data Analyst role where I can turn data into actionable insights and help teams make better decisions. I enjoy working with SQL, Excel, Python, and data visualization, and I’m excited by opportunities to solve real business problems, learn quickly, and work closely with different teams.

Junior Data Analyst turning match and e-commerce data into clear findings with SQL, Python, and Tableau.
United StatesWhat I'm looking for
My La Liga Match Analysis project examined 1,140 matches across three seasons using BigQuery and Tableau. I found that shots on target and home advantage were the strongest predictors of a win.
For my Olist E-Commerce project, I cleaned and merged nine relational tables in Python, handled more than 145,000 missing values, and engineered delivery-time features. The analysis found that delivery time was the strongest driver of customer satisfaction, and I built a Tableau dashboard to show the results.
At Sunrun, I analyzed clients' energy usage data to prepare solar proposals with ROI projections and payback comparisons. I’m transitioning from business operations and consulting into data analytics, supported by my Google Data Analytics Professional Certificate and hands-on project work.
