I am a data analyst with over five years of BI and advanced data systems experience, skilled at translating complex data into actionable insights and scalable solutions that drive business impact.

I specialize in SQL, Python, Tableau, Qlik Sense and AI algorithms, and I have led end-to-end BI project delivery including ETL development, data modeling, automation and governance across multiple organizations.
