Data Scientist
Currentโข Personalised Modelling: Currently developing a Personalised Recommendation Model to allocate tailored offers to customers, closely collaborating with the commercial teams. โข Predictive Modelling: Achieved generosity savings of $18M through the implementation of Predictive Machine Learning Modelling (Random Forest) by identifying risky customer behaviour on average 3 months before the manual intervention.โข Data Preprocessing & Feature Engineering: Improved model accuracy from initial 59% to 88% by employing advanced data preprocessing methodologies, including one-hot encoding, label-encoding, strategic class imbalance techniques, and different feature engineering technologies.โข Data Analysis: Boosted utilisation rate of a recommendation model from 6% to 15% by proactively identifying improvement opportunities through data analysis using pySpark and SQL.โข Cross Functional Team Collaboration: Collaborating with diverse business stakeholders including Data Engineers, MLOps, RPA, and other commercial stakeholders to streamline end-to-end model delivery.โข Data Migration & Leadership: Led a team of 20 people for the successful data and model migration to a new DataBricks platform under tight deadlines.โข Technical Documentation: Documented Technical details of Model Development journey along with reasoning for method selections, feature engineering and future improvement opportunities. Documented Databricks best practices, including cluster configuration, to support the team for optimised DataBricks utilisation.โข Presentation: Presented key ideas of machine learning modelling to various non-technical stakeholders including the CEO of the company.
