Aspiring Data Analyst | SQL • Power BI • Python | Turning operations data into actionable insights

About

I started my career in operations, working closely with processes, reports, and day-to-day business tasks. But over time, I realized something important — we were surrounded by data, yet not fully using it to make better decisions. That curiosity pushed me to explore data analytics. I began with SQL to understand data, moved to Power BI to visualize it, and started using Python (Pandas, NumPy) to analyze it deeper. Today, I approach problems differently: not just what is happening, but why it’s happening and how to improve it. With 4 years of experience as a Senior Process Executive, I bring: Strong understanding of business processes Hands-on experience with data handling and reporting Ability to turn raw data into meaningful insights Currently, I’m transitioning into a Data Analyst role and actively building projects. If you're looking for someone who understands both operations and data — let's connect.
