What I'm looking for

I’m looking to combine my operational experience, analytical training and adaptability in an early-career Data Analytics, Business Intelligence or Operations Analytics role.

My MSc thesis at CCT College Dublin investigated popularity bias in music recommendations. I designed and evaluated a popularity-aware re-ranking approach that increased non-Head recommendation exposure to 41.85%, with an 11.5% held-out Recall@10 trade-off.

For my Ireland Energy Analytics & Forecasting project, I harmonised public datasets and evaluated time-series forecasts. ARIMA(1,0,1) was the best-performing model in the project, and I developed a Dash/Plotly dashboard to communicate trends and forecast uncertainty.

Before focusing on analytics, I worked in inventory, purchasing and business operations, including as a Stock Controller at AyC Soluciones Oleohidraulicas. I’m now looking to combine that operational experience with my analytical training in an early-career Data Analytics, Business Intelligence or Operations Analytics role.
