Hi there! Welcome to my Github Profile! 👋

I’m Ela, a Data Analyst with 8 years of experience. I am very interested in the technical side of this field, so in the future, I want to grow into an Analytics Engineer role. I have worked in different industries – from finance and NGOs to marketing and production. I love analyzing data, finding insights, and creating useful reports and visualizations that help people make better decisions.

I mostly work with SQL, Power BI, Tableau, and Excel, and I am also exploring Python (especially Pandas, NumPy, and Matplotlib).

In my free time, I enjoy playing strategy board games, solving puzzles, and going for long walks.

Check out my Portfolio and see what I’m working on!
