Senior Data Engineer building scalable ETL/ELT and real-time, AI-ready data platforms.
What I'm looking for
I’m a Senior Data Engineer with 7+ years of experience designing scalable ETL/ELT pipelines, real-time streaming systems, and cloud-native data platforms. I specialize in Python, SQL, PySpark, and modern data stack technologies like Snowflake, Databricks, Kafka, and Airflow.
I’ve built and optimized high-volume pipelines processing 2TB+ daily—improving pipeline efficiency by up to 35%, reducing query latency by 40%, and cutting infrastructure costs by 25%. I also bring DataOps and reliability practices using dbt, CI/CD, Docker, Kubernetes, and Terraform, and I enjoy mentoring junior engineers to accelerate delivery.
