What I'm looking for

I am looking for a role that allows me to leverage my analytical skills in a collaborative environment, focusing on data-driven decision-making and continuous learning.

I am a dedicated Data Analyst with a strong foundation in data visualization and analysis. My experience includes creating insightful dashboards and reports that drive data-driven decisions. I have successfully completed various personal projects, such as analyzing sales data for coffee shops and activewear, which have honed my skills in Excel and Power BI.

My recent internship at Cognifyz Technologies allowed me to build Power BI dashboards that analyzed restaurant sales performance, further enhancing my ability to clean and transform datasets. I thrive on turning complex data into clear, actionable insights that support strategic planning and marketing efforts.
