About

I’m a Data Scientist with experience building production-grade ML systems across supply chain, retail/CPG, and e-commerce. Over the last few years, I’ve worked end-to-end across every layer of the analytics lifecycle, right from problem framing and raw data engineering to model development, deployment, and business consumption. My focus areas include: - Demand forecasting & supply planning - Predictive modelling & decision systems - Inventory & replenishment optimisation - MLOps, automation & data pipelines - Business analytics & stakeholder enablement I enjoy solving messy real-world problems where accuracy, impact, and long-term reliability matter. I’m fluent in Python, SQL, PySpark, scikit-learn, TensorFlow/Keras, MLflow, Airflow, and Databricks and I care as much about clean, maintainable code as I do about model performance. At my core, I love using data to build systems that make businesses faster, smarter, and more resilient.
