What I'm looking for

I’m looking to architect governed, high-performance multi-cloud data platforms—modernizing ELT with dbt, delivering real-time pipelines, and enabling business-facing analytics for BI and AI with strong CI/CD practices.

I’m a results-driven Senior Data Engineer with 7 years of experience designing and modernizing scalable, multi-cloud data platforms across GCP and AWS. I transform raw data into reliable insights using Snowflake, dbt, and BigQuery, and I’ve built Medallion Architectures (Bronze/Silver/Gold) to support downstream BI and AI workloads.

In my recent work, I’ve refactored complex legacy SQL into modular transformations, using incremental loading strategies and advanced merge logic for high-performance delivery. I also lead event-driven ingestion with Pub/Sub and Lambda, optimize query performance in Snowflake and BigQuery through partitioning and clustering, and strengthen governance with Git-based CI/CD and schema enforcement—so production systems stay reliable in regulated environments.
