<aside> 👋🏻 Hi there! I’m Yi An.(Andrea)

Hello! I'm a certified Data Analyst with a passion for turning data into actionable insights that drive smarter business decisions. I hold a Bachelor's degree in Computer Engineering and Information from Chung Yuan Christian University, and I have further honed my skills through a comprehensive data analytics program at The Data Analytics Institute in Australia.

As a naturally curious and detail-oriented professional, I thrive on using data to solve complex problems and uncover hidden patterns. My journey into data analytics stems from a lifelong fascination with numbers and their ability to explain real-world phenomena. This has driven me to continually expand my knowledge and expertise in data analysis, visualisation, and business intelligence.
I have hands-on experience with a variety of tools, including Python, SQL, Tableau, Power BI, and Excel. Recently, I completed a Web Traffic Dashboard project, where I analysed user behaviours and created interactive visualisations to provide actionable insights to improve web traffic and engagement. This project is a key example of how I bring value by leveraging data to inform decision-making and optimise performance.
