What I'm looking for

I am looking for a role that fosters growth, collaboration, and innovation in data analytics.

I am a detail-oriented and data-driven aspiring data analyst with practical experience in tools such as Excel, Power BI, and Google Sheets. My proficiency in data cleaning, analysis, and visualization has allowed me to generate actionable insights from real-world datasets. I have developed strong problem-solving skills through hands-on projects and industry-recognized certifications, and I am passionate about using data to inform strategic decision-making.

In my project experience, I successfully cleaned and transformed over 1,000 rows of sales data using Power Query, designed interactive dashboards, and forecasted potential revenue declines. My efforts have led to significant improvements in reporting efficiency and data accuracy, ultimately supporting better decision-making processes. I am eager to leverage my skills and knowledge in a dynamic environment where I can contribute to data-driven strategies.
