2. Machine Learning & Advanced Analytics

- Build, validate, and deploy ML models (classification, regression, anomaly detection, clustering) using scikit-learn pipelines.

- Apply advanced techniques (e.g., Bayesian methods, time-series forecasting, optimization) where needed.

- Ensure robust model validation, drift detection, and performance monitoring.

3. Data Engineering & Cloud Infrastructure

- Design and optimize large-scale data pipelines (batch/streaming) using PySpark, Dask, or Kafka.

- Implement cost-efficient cloud solutions on Azure with CI/CD best practices.

- Write clean, maintainable, and testable Python code following OOP principles and unit testing standards.

4. Stakeholder Communication & Visualization

- Develop interactive dashboards (Streamlit, Plotly Dash, PowerBI) to communicate insights.
