What I'm looking for

I seek remote or hybrid roles where I can lead BI and analytics projects, build predictive models, automate reporting, mentor teams, and deliver measurable operational improvements.

I am a Senior Data Analyst and Business Intelligence specialist with over five years turning complex data into actionable insights that improve operational efficiency and support strategic decision-making.

My work includes building Power BI and Tableau dashboards, designing predictive models in Python and PySpark, automating reporting with SQL and Python, and integrating systems such as Dynamics CRM to improve reporting accuracy and reduce manual workload.

I collaborate cross-functionally with engineers, legal teams, and executives, mentor junior analysts, and deliver analytics that support regulatory review, reduce costs, and improve service outcomes.
