What I'm looking for

I’m looking to build and optimize scalable batch and real-time data pipelines and lakehouse platforms, emphasizing strong data quality automation, streaming reliability, and cost/performance improvements while partnering with analytics and BI teams.

I’m a Senior Data Engineer with 9+ years designing scalable data pipelines, real-time streaming systems, and modern data platforms. I build production-grade batch and near real-time ETL/ELT using Python, SQL, Apache Spark, and Kafka, with deep expertise across AWS, GCP, and Azure.

Most recently, I developed scalable Spark/Kafka-based data pipelines at Square and led migration from legacy on-premise systems to AWS cloud, integrating Microsoft Fabric to improve unified access, governance, and BI enablement. I’m especially focused on data quality automation, monitoring, and distributed query optimization, and I mentor teams while establishing best practices for lakehouse-style architectures.
