> transforming chaos into clarityI’m a Data Science student at the National College of Ireland, focused on transforming data into stories that inform and inspire.
My work blends analytics, visualization, and narrative design — because data should do more than describe; it should connect.

📊 Customer Churn Prediction
Built a complete machine learning pipeline to predict telecom customer churn, including extensive data cleaning, feature engineering, and model comparison (Logistic Regression, Decision Tree, Random Forest). Achieved ~86% accuracy and identified key churn drivers such as contract type and payment method.

🚦 Dublin Traffic Volume Prediction
Applied regression models on Smart Dublin SCATS data (500k+ rows) to predict hourly vehicle volume. Implemented preprocessing pipelines, RFECV feature selection, and 10-fold cross-validation. Gradient Boosting (R²=0.46) achieved the best results, revealing strong temporal and spatial traffic patterns.

📈 AAPL Stock Price Forecasting
Forecasted Apple’s closing stock prices using ARIMA, SARIMA, and LSTM models. Compared statistical vs deep learning approaches on real-world financial data, where LSTM reduced RMSE by 2.5× compared to ARIMA.

Outside of data, I’m always looking for stories and systems — whether that’s through content creation, playing pool, or travelling.
Each of these keeps me curious and grounded:
🎥 Content Creation – I enjoy sharing what I learn and seeing how ideas connect when expressed visually.
🎱 Playing Pool – It sharpens focus, patience, and pattern recognition — skills that overlap surprisingly well with analytics.
🌍 Travelling – Experiencing new places challenges perspective and teaches adaptability, both in life and in problem-solving.
Precision in the data. Personality in the story.
