About this Gig

I build custom machine learning solutions that transform business data into reliable predictions, actionable insights, and decision-support tools.


I develop machine learning models for business applications, including classification, regression, forecasting, customer analytics, fraud detection, and predictive modeling.


My services may include:

  • Data analysis and preprocessing
  • Feature engineering and feature selection
  • Classification or regression model development
  • Model comparison and hyperparameter optimization
  • Cross-validation and error analysis
  • SHAP and feature importance analysis
  • Business-oriented performance evaluation
  • Prediction APIs and Docker configuration
  • Interactive dashboards and monitoring structures
  • Complete source code and documentation


I do not evaluate models using accuracy alone. Metrics such as precision, recall, F1-score, ROC-AUC, PR-AUC, MAE, RMSE, MAPE, and R² are selected according to the business problem and the cost of prediction errors.


Please contact me before ordering when the project involves multiple datasets, unstructured data, data collection, model deployment, large-scale infrastructure, or custom AI agents.
