I'm a Data Analyst

About Me

I’m driven by data and powered by purpose. My journey began in 2019 with Excel and PowerPoint, creating reports to share my findings and insights. Over the years, I became more confident handling data, building my expertise for over 4 years before earning my certification as a Data Analyst two years ago. What started as curiosity, wondering why some businesses thrive while others stall, led me to the world of data analysis, where I now transform raw numbers into narratives that drive action. With hands-on skills in Excel, SQL, Python, and Power BI, I’ve built dashboards that cut reporting time by 60%, uncovered patterns that predicted customer churn, and equipped decision-makers with the clarity to act faster. To me, every dataset tells a story and I’m here to help teams read it, understand it, and use it to move forward smarter.
