Clean, format, and deduplicate small datasets with basic quality checks
In today’s data-driven world, making the right decisions depends on how well you understand your data. I offer professional and reliable data analysis services to help individuals, startups, and businesses transform raw data into meaningful insights that support smarter decision-making.
I work with SQL, Python, Excel, and Power BI to clean, analyze, and visualize data in a clear and structured way. Whether you have messy datasets, large databases, or simple Excel files, I ensure your data is accurate, well-organized, and easy to interpret.
My process begins with understanding your requirements and the goal behind your data. I then perform data cleaning and preprocessing, handling missing values, duplicates, and inconsistencies. Using SQL, I extract and analyze data with advanced queries such as JOINs, GROUP BY, subqueries, and CTEs. For deeper analysis, I use Python (Pandas and NumPy) to identify trends, patterns, and key insights.
I also specialize in Excel-based analysis, including pivot tables, formulas, charts, and summary reports. For visualization and reporting, I create interactive Power BI dashboards that display KPIs, trends, and performance metrics in a visually appealing and user-friendly format. These dashboards help stakeholders quickly understand data and take action.
My services are ideal for students, startups, small businesses, and professionals who need accurate insights without complexity. Whether you need a one-time analysis, a dashboard, or ongoing support, I am committed to delivering results that add real value to your work.
