About Sai Prasad A.

I build and operate production-grade ML platforms on Databricks + AWS—focused on reliability (observability, drift detection, performance), governance (security, lineage), and cost efficiency.Recently at DraftKings, I led platform initiatives including end-to-end model observability (data quality + schema validation, drift detection, performance dashboards/alerts), cost governance that reduced platform spend by ~20%, and lakehouse strategy to streamline ingestion and data availability.Previously at Crown Castle and Sysco, I delivered scalable Spark/Delta architectures, streaming pipelines, and ML workflows with MLflow—improving delivery speed and platform performance.Tech: Databricks, Spark, Delta, MLflow, AWS (S3, EMR, Glue, Kinesis, Lambda), Terraform, Python, SQL.If you’re building an ML platform, modern lakehouse, or cost/quality governance for data + ML, happy to connect.
