Data Scientist

Model Development & Forecasting

• Build, train, and deploy time-series forecasting models using techniques such as:

o XGBoost o Random Forest o Linear regression-based models o ARIMA, SARIMA, Holt-Winters o Prophet / FBProphet

• Operationalize model pipelines using Google Cloud Platform (GCP) services (BigQuery, Cloud Composer, Dataproc, Cloud Run) or equivalent cloud technologies (AWS, Azure).
• Perform feature engineering, hyperparameter tuning, model validation, and continuous improvement of forecasting pipelines.

Data Engineering & Cloud Expertise

• Develop scalable data processing workflows using Python, PySpark, and SQL.
• Work with large datasets and cloud-native data environments for analytics and modeling.
• Collaborate with data engineering teams to ensure robust data pipelines and high-quality training data.

Analytics & Anomaly Detection

• Design and implement data anomaly detection systems to identify volume, pattern, and trend deviations.
• Build automated alerting frameworks for early warning of data or forecast issues.
• Investigate root causes of anomalies and recommend long term fixes.

Accuracy Metrics & Optimization

• Develop and maintain accuracy measurement frameworks (e.g., MAPE, RMSE, MAE, WAPE, Bias).
• Continuously fine tune and optimize model performance based on metric evaluations.
• Communicate model accuracy trends and insights to both technical and business stakeholders.

Domain Expertise - Supply Chain & Demand Forecasting

• Apply strong domain knowledge in retail supply chain, inventory planning, replenishment, and demand forecasting.
• Partner with business teams to translate forecasting needs into data science solutions.
