What I'm looking for

I seek senior roles designing governed, scalable analytics platforms where I can lead teams, improve data quality, and deliver executive-grade insights for business impact.

I am a Senior Business Intelligence Engineer with 15+ years building and scaling enterprise analytics platforms across cloud, finance, and supply-chain domains, turning ambiguous business problems into governed data products used by hundreds of stakeholders.

I design dimensional data models and ETL/ELT pipelines, build executive-facing dashboards, and lead teams to improve data quality and delivery reliability. My work has reduced reporting turnaround time and production defects while enabling senior leadership to make data-driven decisions.
