What I'm looking for

I’m looking to build reliable, scalable, AI-ready data platforms—leveraging lakehouse architectures, DataOps, and real-time analytics to help teams make data-driven decisions at scale while improving performance and cost efficiency.

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.
