What I'm looking for

I seek a data engineering role focused on cloud-native ETL, data platform modernization, and building AI-ready pipelines within collaborative teams that value data quality, governance, and measurable performance improvements.

I am an AWS Certified Data Engineer with 6+ years building scalable, cloud-native data pipelines and enterprise data warehouses for financial services, healthcare, and retail. I specialize in AWS (Glue, Redshift, S3), Snowflake, Informatica, CDC, and performance-focused ETL/ELT design, having processed over 9 billion records while ensuring data quality, governance, and regulatory compliance.

I have led cloud migration and modernization efforts—architecting Glue/Redshift solutions, implementing reusable pipeline components that cut development time by 30%, and automating scheduling and monitoring to improve SLAs. I partner closely with analysts, BI teams, and stakeholders to translate business needs into robust data models and production-ready pipelines that enable analytics and AI/ML consumption.
