Polina Tretakova

I’m an aspiring Junior Data Analyst with practical SQL and Excel experience built through educational projects. I focus on turning structured data into clear reporting and actionable insights.

In my Flight Database Analysis project, I queried airline and passenger databases using SQL. I used filtering, sorting, grouping, aggregation, and generated reports from structured datasets to extract business-relevant takeaways.

With my Excel Data Analysis work, I built pivot tables and analytical reports. I handled formulas and large datasets to organize, analyze, and visualize information for effective reporting.

I’m also strengthening my SQL fundamentals through practice projects, using SELECT, WHERE, GROUP BY, HAVING, and JOIN to uncover insights in a consistent, detail-oriented way. I’m open to internships and entry-level remote roles where I can grow my analytical expertise and support business decision-making.
