What I'm looking for

I seek remote roles where I can build scalable ETL pipelines, data warehouses, and dashboards; value clear documentation, data quality, and collaborative, autonomous work.

I am a detail-oriented, self-driven data analyst and analytics engineer with hands-on experience building end-to-end data pipelines, data warehouses, and interactive dashboards. I deliver clean, reliable insights using Python, SQL, and Power BI to support data-driven decision-making and financial analytics.

I have architected Medallion-style data warehouses, automated ETL with T-SQL and Python, and developed scalable stock analysis pipelines for over 200 equities, producing risk-adjusted metrics and dynamic Power BI visualizations. I prioritize documentation, data quality, and cross-functional collaboration to ensure maintainable, production-ready analytics solutions.
