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 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.

Cover image for While working on a project,
While working on a project, one question always comes first: Do we need data first… or a clear understanding of the requirement? It’s easy to jump into dashboards, charts, and analysis. But without clarity, even the best data can lead in the wrong direction. So the real focus is asking the right questions: 👉 What exactly is the goal? 👉 What decision needs to be made? 👉 What does success look like? When the requirement is clear, the data becomes powerful. That’s how analysis turns into real business impact.
