IrelandWhat I'm looking for
I am a Senior Data Scientist with extensive experience in developing machine learning models and optimizing data pipelines. Currently, I work at Optum, where I have successfully implemented a machine learning model using LightGBM to forecast claim rejections and automated processes using Generative AI. My role involves mentoring team members and leading training sessions on Azure Databricks, ensuring best practices in coding and data management.
Previously, I served as a Data Scientist II at Optum, where I developed metrics to optimize the revenue cycle and transitioned complex workflows from SQL to PySpark. My journey began with a Data Science internship at CeADAR, where I contributed to innovative projects such as a classroom response system using computer vision. My educational background includes a Master’s degree in Computer Science from University College Dublin, where I graduated with First Class Honors.
