About me

  • I'm a self-taught data analyst with a passion for solving real-world problems using data. I specialize in turning raw data into actionable insights through data cleaning, analysis, and visualization. My projects showcase my ability to work with tools like Python, Pandas, Excel, and Power BI, and apply techniques such as data wrangling, exploratory data analysis (EDA), and dashboard creation. I've built interactive dashboards and worked on data-driven projects related to customer behavior, credit risk, and sales trends. You can explore my work on the Projects page. Currently, I'm seeking a remote data analyst role where I can contribute to data-driven decision-making and continue growing my skills in analytics, SQL, and machine learning.
