I am Kacper Kowalski
Data Science & Artificial Intelligence Undergraduate Student
About me

I am a Data Science & Artificial Intelligence undergraduate with hands-on experience building machine learning and reinforcement learning projects in Python. My work focuses on correct problem formulation, state and feature design, evaluation methodology, and reproducible experiments.
I have built projects including a tabular Q-learning Snake agent, an end-to-end heart disease prediction pipeline with leakage prevention and explainability, and a thermodynamic jet engine performance simulator. I am seeking graduate or entry-level roles where I can contribute to real ML and data-driven systems while continuing to develop under experienced engineers.
