What I'm looking for

I seek cloud-focused data engineering roles building secure, automated ETL and analytics platforms with strong collaboration, compliance emphasis, and opportunities to improve performance and delivery through DevOps and data architecture.

I am a Senior Data Engineer with five years of experience designing and maintaining scalable data pipelines across banking and healthcare domains.

I specialize in cloud-native ETL and data platform work using AWS, Azure, and GCP—building automated, event-driven ingestion, transformation, and cataloging solutions with tools like Glue, ADF, Databricks, Airflow, and Terraform.

My projects emphasized compliance and security (HIPAA, GDPR, PCI-DSS), improved processing performance (examples: 35% faster retrieval, 40% faster PySpark jobs), and reduced reconciliation and release cycles through automation and best practices.

I deliver production-ready data marts, dashboards (Power BI, Tableau, QuickSight) and containerized services with CI/CD, and I collaborate closely with stakeholders to translate business needs into reliable analytics and operational data products.
