Profile: https://flows.cv/sushmahiremath

I am a Senior Principal Consultant and Lead Data Engineer with 11+ years of experience building data platforms on AWS, GCP, Databricks, and Snowflake. I specialize in modernizing legacy systems, designing scalable ETL pipelines, and enabling faster reporting and analytics for business teams.

Over my career, I’ve led cloud migration programs, reduced processing costs and timelines through Spark optimization, and delivered data lakes that support financial, healthcare, and regulatory needs. I also enjoy mentoring engineers, improving delivery practices, and working closely with stakeholders to align technology with business goals.

I’m always open to connecting with peers, leaders, and organizations driving cloud and data transformation.
