I build governed, high-performance data platforms and semantic APIs for enterprise analytics.

I've built governed data platforms and semantic APIs at Aisera and Bain & Company, using AWS AppSync, GraphQL, Lambda, Kinesis, Snowflake, DynamoDB, and S3 to support analytics, RAG workflows, and real-time event processing.

Across Bain and Amazon, I've delivered scalable ETL pipelines, analytics-ready data models, and warehouse optimizations that cut reporting preparation time by 40%, improved dashboard load times by 60%, and reduced analytical workload costs by 25%. I also lead data governance, mentor engineers, and build reliable CI/CD and data quality practices.
