What I'm looking for

I’m looking for a role where I can design and optimize scalable data systems—fast, cost-efficient, and reliable—using modern tools, collaborating closely with stakeholders, and continuously learning to deliver measurable business value.

I’m a Data Engineer who designs and optimizes robust data systems that deliver fast, cost-efficient, reliable data solutions with real business impact. I stay committed to continuous learning and leverage cutting-edge technologies to turn data into actionable decision-making.

At Strata Analytics, I lead the development of scalable BigQuery and Dataform data models and team initiatives to replicate data models across regions. I’ve built cumulative models that prevent reprocessing 90–120 days of data daily—reducing compute by 65% and storage costs by 30%—and improved analytics experiences like a Streamlit app with 75% lower load times.
