Data Engineering Lead building scalable streaming and batch platforms to reduce ETL latency and power product analytics.
IndiaWhat I'm looking for
I’m a Data Engineering Lead with 9+ years of experience designing and optimizing scalable data platforms and pipelines at enterprise scale. My focus is reducing ETL processing time while enabling real-time and batch, data-driven decision-making.
At Cisco, I lead initiatives that improve analytics workflows and data quality using Python, Spark, Trino, Datahub, Pinot, SQL, and modern streaming patterns. I’ve implemented solutions that help teams analyze conversion rates and identify bottlenecks for product improvement.
Previously, I led ETL migrations and pipeline modernization efforts, including achieving a 35% reduction in ETL processing time. I also designed funnel progression analysis datasets and built real-time and batch Data/ETL pipelines for people analytics using SQL, Python, Spark, Airflow, AWS (S3 and Kinesis), DBT, and Databricks.
I care about robust engineering practices—cross-functional collaboration, Agile methodologies, CI/CD, and clear data modeling through ERDs. I’m also passionate about cloud-native, innovative solutions (including Azure Data Engineering certification) that support business objectives and deliver measurable impact.
