What I'm looking for

I seek a collaborative analytics role where I can build KPI-driven dashboards, automate reporting, and use SQL/Power BI/Python to drive data-led decisions and measurable business improvements.

I am a data analyst with an MSc (Distinction) in Management and a strong background in economics, specializing in turning complex datasets into actionable business insights using SQL, Power BI, Excel and Python. I have a proven record of improving reporting efficiency by 40%, automating manual processes to reduce data processing time by 30%, and delivering KPI-driven dashboards that enhanced decision accuracy.

My experience spans healthcare analytics and cross-functional collaboration where I designed dashboards tracking 50+ patient clinical KPIs, automated weekly reporting to increase staff efficiency, and managed large-scale data cleaning and validation to ensure regulatory compliance. I focus on data storytelling, stakeholder communication and delivering measurable performance and cost-efficiency gains through analytics.
