What I'm looking for

I'm looking for a data analytics or machine learning role where I can build reliable data products, improve data quality, communicate insights clearly, and grow into cloud deployment and MLOps.

I've built Power BI dashboards and SQL reporting at Ditinex Enterprise, helping management track project status, resource utilisation, issue resolution, and milestones across 8–10 concurrent client projects. My work reduced weekly reporting preparation by 4–6 hours per cycle and cut reporting discrepancies by approximately 25%.

I build supervised learning pipelines in Python, including a fraud detection project on 594,000 transactions that achieved 0.96 AUPRC and 0.99 AUROC on unseen later periods. I use out-of-time evaluation to control temporal leakage, tune LightGBM and XGBoost with Optuna, and serve trained models through FastAPI.

I'm completing an MSc in Data and Computational Science at University College Dublin and extending my work into cloud deployment and MLOps. I enjoy reconciling conflicting data, defining trustworthy KPIs, and translating analysis for engineers, QA teams, delivery managers, and decision-makers.
