What I'm looking for

I seek senior roles building scalable cloud data platforms and pipelines, with strong engineering practices, automation, and cross-functional collaboration to enable analytics and ML.

I am a Senior Data Engineer with 8+ years building and scaling cloud-native data platforms using Python, SQL, Spark, Airflow, Kafka, dbt, Databricks, and Snowflake. I design reliable real-time and batch pipelines across AWS, Azure, and GCP, deliver BI solutions with BigQuery, Snowflake, Tableau and Power BI, and implement CI/CD and observability to accelerate deployments and improve reliability.

I have led engineering teams, mentored engineers, and driven migrations and modernization at enterprise scale—reducing latency, cutting infrastructure costs, and improving data reliability to 99.9%. I prioritize clean data architecture, automation, and cross-functional collaboration to enable analytics, attribution modeling, and ML workflows.
