Professional summary (Data Analysis)

I am gaining practical experience in data analysis by working with real-world datasets across the sales, e-commerce, and healthcare domains. My work focuses on transforming raw datasets into clean, structured, and meaningful insights that support business and operational decision-making.

Through these projects, I have practised data cleaning, exploratory data analysis, dashboard creation, visual storytelling, business question analysis, and report writing using tools such as Microsoft Excel, Google Sheets, Pivot Tables, charts, formulas, dashboards, and document-based reporting.

My approach is centred on understanding the business problem first, preparing the data properly, analysing patterns, creating clear visualisations, and presenting insights in a way that non-technical stakeholders can understand.

Core strengths

• Data cleaning and preparation (missing values, duplicates, inconsistent formats, incorrect data types)
• Exploratory Data Analysis (trends, patterns, outliers, relationships)
• Dashboard development (KPI cards, charts, filters/slicers, trend views, breakdowns)
• Business intelligence reporting (written insight reports + recommendations)
• Data visualisation (clean, consistent chart design and visual storytelling)
• Spreadsheet analytics (PivotTables, formulas, helper/calculated columns)
