About this service

Sitting on data but not turning it into decisions? I build machine learning models for prediction, forecasting, classification, and recommendation, fully tailored to your dataset and goal.

  • Data cleaning, feature engineering, and exploratory analysis
  • Model selection and training (XGBoost, scikit-learn, neural nets)
  • Regression, classification, time-series forecasting, churn, and more
  • Evaluation, cross-validation, and clear performance reporting
  • Deployment as an API or notebook with documentation

As a data scientist with years of applied ML experience, I focus on models that generalize and deliver business value, with honest metrics and no overfitting tricks.

Share your dataset and the question you want answered, and I'll outline the approach and expected outcomes. Let's turn your data into predictions you can act on.

Kyiv-based machine learning engineer building computer vision, NLP, and recommendation systems. I turn messy data into reliable models and ship them with clean APIs. Strong in Python, PyTorch, and cloud deployment. I value precision, documentation, and meeting deadlines even under pressure.
