Data Scientist
Pet-project, Berdychiv | January 2026 - February 2026

Implemented predictive modeling techniques using Python (Scikit-Learn), specifically
focusing on Ridge, Lasso, and Elastic Net regression to handle overfitting and improve
model accuracy, as covered in Aurélien Géron's 'Hands-On Machine Learning'. Additionally, I
acquired a foundational understanding of financial markets, arbitrage, and the mechanics
of forward and futures contracts by studying the core principles in John Hull’s 'Options,
Futures, and Other Derivatives'. This combined approach allows me to apply statistical
learning methods to financial and logistics data analysis
