Power BI Data Analyst turning data into insights
Cover image for Medicine Supply Chain Disruption Predictor Built
Medicine Supply Chain Disruption Predictor Built a production-ready ML system that predicts drug shortage risk using real FDA data. Collected and cleaned 1703 real drug shortage records, trained an XGBoost model, and deployed it as a live REST API — accessible to anyone worldwide. The biggest challenge was identifying and removing 6 sources of data leakage that were causing fake 100% accuracy. After fixing this, the model delivers honest, generalisable predictions. The entire system is containerised with Docker, automatically rebuilt and redeployed via a Jenkins CI/CD pipeline on every code push, and visualised through an interactive Power BI dashboard. Result: A complete ML + DevOps project — from raw data to live deployed API — built independently in under 2 weeks.

Cover image for Transform Your Analytical Skills with Business Insight Mastery
The biggest shift in my learning hasn’t been technical it’s been mindset. I used to think good analysts are the ones who know more tools. Now I realize they’re the ones who understand the business better. Anyone can create charts. Not everyone can explain why it matters. That’s what I’m working on every day.

Cover image for Data is useless. Yes, it
Data is useless. Yes, it is. Because on its own, it doesn’t say much. It’s just numbers, rows, and columns. The real value comes when that data is understood — when it answers a question, shows a pattern, or drives a decision. That’s what turns data into information. And that’s what businesses actually need.
