NetherlandsWhat I'm looking for
As a dedicated Data Scientist, I have been working at Athlon Car Lease International B.V. since January 2021, where I design and implement machine learning models to predict residual values of cars and repair maintenance costs. My expertise lies in developing predictive models using supervised learning algorithms such as XGBoost, as well as applying unsupervised learning techniques like Hierarchical Clustering to uncover patterns in complex datasets.
In my role, I prioritize data quality by cleaning and preprocessing large datasets using Python, R, and PySpark. I also create interactive dashboards and reports with Power BI to visualize key business metrics and trends, making insights accessible to non-technical stakeholders. My experience includes deploying and maintaining machine learning models in production environments using cloud-based platforms like Azure and Databricks, ensuring efficient automated pipelines.
