About Me
I turn data into decisions.
Hi, I’m George — I use SQL, Python, and Power BI to build forecasting models, automate analysis, and deliver insights teams can act on immediately.
Focus Areas
  • Energy analytics
  • AI-driven automation
  • Secure and reliable data workflows
I care about clarity, speed, and solving the real business problem — forecasting demand, spotting bottlenecks, improving efficiency, or reducing risk.
If you need data to guide the next move, you’ll find useful work here.
Projects With Real Business Impact
Every project here solves a concrete business problem and ends with clear, actionable insights.
  • Reduced false positives with ML-based fraud detection
  • Improved energy planning with clean-energy forecasting
  • Identified revenue opportunities with mobile app market analysis
  • Supported sustainability decisions using data-center energy dashboards
My approach:
Start with a real question ➝ analyze what matters ➝ deliver insights that drive decisions.
No fluff. No academic exercises.
Just practical work built for real outcomes.
Solar Energy Forecasting
Cutting-edge forecasting for clean energy
  • Built a Prophet model to predict hourly solar generation with strong short-term accuracy
  • Designed a Power BI dashboard comparing forecast vs. actuals to surface underperformance patterns
  • Helped stakeholders plan energy usage more effectively with clearer forecasts
Credit Card Fraud Detection
Reducing false positives and improving financial trust
  • Trained and compared classification models (LogReg, RF, XGBoost) on imbalanced payment data
  • Applied SMOTE + tuned hyperparameters → improved recall and reduced false positives
  • Delivered a clean insights report showing where financial teams could tighten controls
Google Play Store Apps Analysis
Finding growth opportunities in app performance
  • Analyzed 10,000+ apps for pricing, downloads, ratings, and performance patterns
  • Identified which app categories consistently outperform others
