About Me
👋 Hi, I’m George — a data analyst focused on turning complex datasets into clear, actionable insights.
I work with Python, SQL, and Power BI to build end-to-end projects that combine analysis, forecasting, and visualization. My portfolio includes energy forecasting, fraud detection, and app analytics — all aimed at solving real-world problems.
I’m especially excited about the intersection of clean energy and AI, and my goal is to use data to support smarter decisions in industries that shape the future.
Welcome to my portfolio — feel free to explore my work, and let’s connect if you share similar interests.
Projects that tell a story
Each project I’ve built connects to a bigger question: how can data help solve real problems?
  • From fraud detection that improves financial trust,
  • To clean energy forecasting that supports sustainability,
  • To app performance insights that improve everyday user experience,
  • To data center energy dashboards that highlight the impact of renewables.
Together, these projects show how I approach data: start with a real-world question, explore the numbers, and finish with insights people can act on.
