What I'm looking for

I’m looking for a role where I can use SQL, R, and Python to deliver clean, reliable insights—supported by EDA and clear visualization—while growing in business intelligence and analytics reporting for better decision-making.

I’m a freelance Data Analyst with hands-on experience in R, Python, and SQL for data cleaning, analysis, and visualization. I specialize in transforming raw datasets into clear, actionable insights through exploratory data analysis (EDA) and effective data storytelling.

Through projects such as retail Superstore sales analysis, customer and time-based sales trends, and hospital patient record analysis, I clean and transform data, identify key patterns, and build visual reports to support decision-making. I use SQL for querying and data extraction, and tools like ggplot2 and other visualization libraries to clearly communicate insights.

I have strong working knowledge of SQL for data analysis and am currently strengthening my expertise in business intelligence, analytics reporting, and machine learning fundamentals. My focus is on delivering accurate, high-quality analysis that turns complex data into simple, useful insights for decision-making.
