What I'm looking for

I seek a collaborative role applying ML and data analysis to solve business problems, with mentorship, growth opportunities, and impactful projects.

I am a motivated, detail-oriented junior data scientist with strengths in data mining, statistical analysis, and machine learning. I build and fine-tune predictive models (classification and regression), visualize model performance, and communicate findings to stakeholders to drive business decisions.

My projects include high-performing churn prediction, NLP sentiment analysis, and vehicle price prediction using CatBoost, XGBoost, LightGBM, BERT and scikit-learn; I pair technical work with strong collaboration, reporting, and a continuous curiosity to learn new tools.
