What I'm looking for

I’m looking for a senior BI/data engineering role where I can modernize governed analytics platforms, accelerate self-service decision-making, and deploy AI-augmented insights—while partnering across business teams and mentoring data talent.

I’m a results-driven Senior Business Intelligence & Data Engineer with 8+ years transforming enterprise data into actionable intelligence across financial services, retail, and technology. I architect end-to-end analytics ecosystems—using Databricks, Snowflake, Tableau, Power BI, dbt, Alteryx, and Azure—to deliver revenue growth, operational efficiency, and self-service decision-making.

Most recently, at JPMorgan Chase, I led analytics modernization, building governed Tableau + Snowflake + dbt pipelines and launching an AI-augmented BI pilot with Tableau Pulse and ChatGPT-powered insight summaries. I modernized legacy ETL by migrating from SSIS to Alteryx + dbt + Snowflake, improving pipeline reliability (reducing failures by 40%) and strengthening data quality through dbt testing/CI/CD workflows (reducing production incidents by 35%); I also created enterprise KPI governance across 6+ departments with RBAC and RLS, reducing manual reporting effort by 50% and improving reporting accuracy and cross-team trust.
