What I'm looking for

I seek senior engineering roles designing scalable, secure cloud data platforms with strong CI/CD, automation, and collaborative, compliance-focused teams.

I am a Senior Data Engineer and Cloud Data Architect experienced in designing and delivering scalable ETL/ELT pipelines, cloud migrations, and data warehouses across AWS, GCP, and Azure. I specialize in Python, SQL, Airflow, dbt, Snowflake, and BigQuery, and have led initiatives that improved query performance, reduced costs, and ensured HIPAA/GDPR compliance.

I have driven end-to-end data platform projects—from streaming Kafka pipelines and real-time analytics to CI/CD automation with Terraform and GitLab—while mentoring teams and collaborating with product and security stakeholders to translate business needs into reliable production systems.
