What I'm looking for

I seek roles building and operating secure, scalable Azure lakehouse platforms where I can improve data quality, governance, and performance while enabling analytics and ML teams.

I am a Senior Data Engineer with 6+ years building secure, scalable Azure-based data platforms across healthcare and insurance, focusing on lakehouse and analytics architectures using Databricks, Delta Lake, and Synapse. I design and optimize Spark batch and streaming pipelines, implement dbt transformation layers, and automate infrastructure with Terraform and CI/CD to deliver analytics-ready datasets that support BI and data science.

I prioritize data quality, governance, and regulatory compliance (HIPAA, audit-ready pipelines) while enabling self-service analytics and ML experimentation. My work has reduced pipeline runtimes and failures, improved observability and lineage, and supported thousands of internal users with predictable performance and data freshness SLAs.
