Senior Data Engineer building cloud-native ELT, streaming, and lakehouse platforms that cut latency and costs.
IndiaWhat I'm looking for
I’m a Senior Data Engineer with 6+ years architecting cloud-native ELT/ETL pipelines, real-time streaming systems, and lakehouse platforms at enterprise scale. I focus on measurable outcomes—cost reduction, latency improvements, and data quality uplift—across AWS, Snowflake, and Databricks ecosystems.
I build production-grade data foundations using Apache Airflow, dbt, PySpark, and Apache Kafka, with strong DataOps, data observability, and data governance practices. In my current role, I’ve architected 30+ modular ELT pipelines on Snowflake, cutting compute spend by 35% and reducing end-to-end latency from 4 hours to under 30 minutes.
I also deliver governed lakehouse architectures with Databricks Delta Live Tables, medallion (Bronze/Silver/Gold) patterns, Unity Catalog, and reliability-focused orchestration—achieving 99.9% pipeline uptime and enabling schema evolution without downstream breakage. Previously, I led Oracle-to-Redshift migration (>$200K annual savings) and Netezza-to-Snowflake cloud migration (>$150K annual savings), and I hold SnowPro Core, Databricks Data Engineer Professional, and AWS Data Analytics – Specialty certifications.
