What I'm looking for

I’m looking for a team where I can architect scalable lakehouse pipelines, build reliable DAG-based orchestration, and integrate LLM/AI enrichment—while owning data governance, performance tuning, and measurable KPI outcomes.

I’m a Senior Analytics Engineer and Data Architect with over 15 years of experience across the Modern Data Stack, focused on architecting scalable Medallion (multi-layered) Data Warehouses and ELT/ETL pipelines. I build workflow-orchestrated DAGs with Apache Airflow and deliver analytics-ready data with dbt and PySpark (Apache Spark), optimizing models like Star/Snowflake schema for real business intelligence.

I’ve specialized in Cloud Data Lakehouses—Microsoft Fabric (OneLake), Snowflake, and Azure—and I integrate AI (OpenAI/LLM) into Python pipelines to automate enrichment and support downstream Machine Learning readiness. I also modernize legacy environments into automated, secure, GDPR-aligned data ecosystems, using rigorous data profiling, validation frameworks, and data governance while collaborating across engineering teams as a technical leader.
