What I'm looking for

I seek roles where I can lead BI and data engineering projects, drive scalable data architectures, mentor teams, and deliver high-quality analytics solutions within organized, outcome-focused environments.

I am a Senior Business Intelligence and Data Engineering professional with over seven years designing, building, and maintaining data architectures for analytics, reporting, and data warehousing. I lead full-cycle projects from requirements and data modeling to ETL/ELT development, testing, documentation, and production deployment.

I have delivered high-performance, scalable solutions using tools including Azure Data Factory, Databricks, NiFi, Teradata, SQL Server, Power BI and Qlik, and languages such as PySpark, Scala and Python. I have led teams, coordinated schedules with Gantt charts, ensured direct client communication, and owned data model and semantic layer design.

I focus on technical leadership, data quality, and organized execution to produce measurable results and reliable analytics platforms. I seek to contribute my BI and data engineering expertise to teams that value technical robustness and outcome-driven delivery.
