Snowflake data engineer delivering scalable ELT pipelines and governance.
IndiaWhat I'm looking for
I am a Snowflake Data Engineer with 6+ years in IT and 4+ years focused on data engineering, building scalable ELT pipelines and analytical datasets for enterprise analytics.
I design data models, optimize warehouse performance, and implement secure, governed data platforms using Snowflake, dbt, Fivetran, Prefect, ADF and related tools. I’ve migrated enterprise systems to Snowflake and improved data reliability and reporting consistency across business teams.
My work emphasizes performance tuning, robust data ingestion (Snowpipe, REST APIs, automated connectors), and implementing RBAC, row-level policies and masking to meet governance and security needs. I mentor junior engineers and maintain clear documentation to enable cross-functional collaboration.
I deliver measurable improvements—faster refreshes, fewer load failures, and optimized compute usage—while focusing on quality, observability, and scalable practices that support finance and product analytics stakeholders.
