What I'm looking for

I seek a hands-on data engineering role where I can design scalable ETL and database solutions, improve performance, and collaborate cross-functionally.

I am a Senior Data Engineer and SQL Server developer with 12+ years building and optimizing enterprise database systems, ETL pipelines, and reporting solutions that reduce manual work and improve accuracy. I design and deploy scalable SSIS/T-SQL solutions, perform deep performance tuning, and integrate heterogeneous data sources to deliver high-performance, production-ready systems.

I have led major migrations, built automated commission-processing platforms, and resolved critical production performance issues that improved ETL and reporting performance by 30–70%. I consistently collaborate with stakeholders across development, QA, and leadership, and I bring a pragmatic, results-driven approach to designing resilient data platforms.
