About Me

Hi, I’m a data analyst with a background in management accounting and a passion for clean data and clear insights. I use tools like Excel, SQL, Power BI, Tableau, and more to bring numbers to life.

Supermarket Sales Analysis

(Excel + Power BI)

Analyzed supermarket sales using Excel and visualized trends in Power BI. This project covers KPIs like revenue by customer type, best-selling product lines, and peak sales periods. It was my first end-to-end dashboard combining manual cleaning with interactive visuals.

Customer Retention Analysis

(SQL + Tableau)

Using the Telco Customer Churn dataset, I cleaned and queried data using SQL (SQLite) and built dashboards in Tableau. I explored patterns in churn behavior across contract types, tenure, and internet service categories.

GitHub Pages Site Builder

(HTML + GitHub Pages)

I created this site using the Dimension theme from HTML5 UP and hosted it on GitHub Pages. I learned how to edit HTML/CSS, fix mobile responsiveness, and customize each section to reflect my work and personality. This project shows my commitment to learning new tools and presenting myself professionally online.
