Data & AI Engineer
Hemant Kumar
I build production systems, AI agents & real-time pipelines.
I build large-scale production systems, AI agents, and real-time event-driven pipelines — end to end, from React frontends to distributed backends. 15+ years across full-stack and distributed systems engineering, now applied to LangGraph, AWS Bedrock, Kafka, and modern data stacks. Software Engineer III @ JPMorgan Chase.
