What I'm looking for
I am a data analyst with practical experience transforming complex datasets into executive-level insights using Power BI, SQL, Excel and automation. I manage the full data lifecycle from collection and cleaning to modeling, QA, and visualization.
At Great Health Care I designed end-to-end analytics workflows, developed custom DAX measures, built scalable data models, and automated reporting with Power Automate to deliver consistent, actionable dashboards for stakeholders.
Previously I contributed to software development and agile delivery at Afiniti, coaching teams on Scrum practices and supporting product and release planning. I also led content strategy and technical writing for Skills Training Program and produced SaaS reviews for All That SaaS.
My MSc dissertation applied Python, pandas and scikit-learn to customer churn prediction, delivering ~85% accuracy with Logistic Regression and Random Forest and producing clear visualizations and customer segmentation to support business decisions.
