I’m a Data Analyst and recent BCA graduate with hands-on experience turning messy data into clear, decision-ready insights. I work across SQL, Python, Power BI, and Excel, with a focus on data cleaning, exploratory data analysis (EDA), and business reporting.

Through the Deloitte Australia Data Analytics Virtual Internship (Forage), I cleaned, transformed, and analyzed business datasets using SQL and Microsoft Excel. I also wrote SQL queries with joins, filtering, and aggregation to support stakeholder reporting, producing actionable analytical reports and trends.

In my HR Analytics Employee Attrition Dashboard project, I built an interactive dashboard using Excel, SQL, and Power BI, including 10+ KPIs, charts, slicers, and DAX measures. I identified key attrition drivers such as overtime, salary, experience, job role, and employee satisfaction to support retention and workforce planning.

For my Customer Churn Analysis, I used Python with Pandas and Matplotlib to perform data cleaning, preprocessing, and EDA on churn datasets. I created 5+ visualizations and analyzed churn patterns across contract type, customer segment, monthly logins, and customer satisfaction—then delivered data-driven recommendations to improve retention.
