I’m a Data Engineer building reliable healthcare pipelines on Databricks and AWS.
IndiaWhat I'm looking for
I’m a Data Engineer with nearly 3 years of production experience building healthcare pipelines at Perficient, where I currently work on a Medicare Advantage billing and reconciliation engagement. I’m hands-on with Databricks, SQL, Spark SQL, Delta Lake, AWS (S3, Redshift), and PySpark, plus Stonebranch for orchestration, and I bring a Databricks Certified track record focused on pipeline reliability.
I lead production root-cause analysis and data quality validation across member eligibility, billing, and reconciliation workflows—building control-file validation frameworks, designing historical data backfills, and improving performance by resolving Redshift WLM timeouts tied to SCD2 joins. I also manage end-to-end release activities (JAR packaging, S3 deployment, Stonebranch job migration, Git version control) and support teams through structured knowledge transfer, earning Perficient milestone performance awards in Q1 2024 and Q1 2025.
