What I'm looking for

I’m looking for a team that values scalable lakehouse engineering in Microsoft Fabric/Azure. I want to lead ETL/ELT modernization, optimize Delta/Spark performance, and deliver semantic models that executive teams trust—while strengthening delivery with CI/CD and mentoring.

I’m a systems engineer turned Senior Data Engineer with 10+ years focused on data engineering and cloud infrastructure. I design and operate ETL/ELT pipelines in Microsoft Fabric, Azure, and Databricks, with a strong emphasis on Medallion (Bronze/Silver/Gold) patterns and Delta table management at scale.

Across migrations and ongoing optimization, I’ve led platform transformations that reduce processing time (25%) and improved pipeline reliability by automating Delta-table validations. I also streamline delivery with CI/CD using GitHub and native Git integration in Fabric workspaces, while tuning Spark and Synapse for major query-time reductions.

I provision semantic models and curated datasets for executive reporting in Power BI using DAX and Power Query—without getting pulled into dashboard visual design. I’ve also trained junior engineers and guided learners on Python, SQL, and Power BI projects, blending engineering rigor with practical, teachable delivery.
