What I'm looking for

I’m looking for a team where I can own lakehouse/data-mesh solutions on Azure (Fabric/Databricks), build trusted fact/dimension models and ingestion pipelines, and collaborate closely to deliver business metrics that Power BI users can rely on.

I’m a Data Engineer specializing in Microsoft Fabric and Databricks on Azure, with deep experience in Lakehouse and Medallion architectures. At EY, I’m currently designing fact and dimension tables, ingestion pipelines, and business metrics for a Finance engagement in the Gaming/Entertainment industry.

I build end-to-end lakehouse solutions using Medallion architecture (Bronze/Silver/Gold) within a Data Mesh of domain-aligned workspaces. I focus on metric engineering and dimensional modeling (star schema) so Power BI reports and KPI dashboards have trustworthy, production-ready data.

Across cross-industry work in automotive, banking, telecom, and logistics, I’ve delivered reliable ETL/ELT pipelines and supported data quality through exploratory analysis before production. I’ve also built ETL workflows with Pentaho and even supported a GenAI/RAG prototype integrated into existing pipelines, while working directly with client constraints around compliance and source complexity.

My background also includes large-scale Databricks processing with Apache Spark, Azure Data Lake Gen2 storage, and helping migrate workloads from Synapse to Databricks for better performance. I bring strong engineering fundamentals—from SQL optimization and Power BI (DAX/Power Query) to backend work with Django and DevOps support—and I’m Microsoft Certified: Fabric Data Engineer Associate (DP-700).
