PROFILE
Egor Dmitriev
Contributed to the OpenSTEF/openstef repository by delivering robust data engineering and machine learning features over four months. Developed data balancing for prediction training and implemented a FeatureClipper to improve model stability, both using Python and Scikit-learn. Enhanced forecast interpretability by building quantile-based load forecast visualizations with Plotly, and improved CI/CD reliability through maintenance and licensing updates. Addressed a late-binding bug in holiday feature generation, optimizing feature engineering workflows and test coverage. Standardized issue templates to support project management and compliance, ensuring consistent documentation and governance. Work demonstrated a focus on reliability, reproducibility, and maintainability across data-driven forecasting pipelines.
