What I'm looking for

I seek a data-focused role where I can build scalable analytics and automated reporting, collaborate cross-functionally, and drive strategic, measurable business impact.

I am a Senior Data Analytics Engineer with 10 years of experience building scalable analytics solutions, KPI tracking systems, and executive dashboards across SaaS and enterprise environments.

I specialize in SQL, Python, Tableau, and Excel to analyze volume, market, and geographic trends, and I have repeatedly reduced reporting latency and manual effort through query optimization and automation.

My work spans ETL development, data governance, and performance optimization—enabling accurate, auditable consolidated warehouses and reliable integrations with CRM and finance systems.

I partner with product, finance, and operations leaders to translate complex datasets into strategic recommendations that drive cost reduction, improve KPI visibility, and support data-informed decision making.
