Hi, my name is

Hitesh Lenin.

I architect agentic AI & cloud-native ML platforms.

Senior AI/ML Architect with 11+ years shipping production-grade GenAI, agentic AI, and lakehouse data platforms on AWS, Azure, and Databricks across manufacturing, insurance, finance, healthcare, and retail.

⚡ AWS & Azure

Architect of production-grade AI.

I design and ship agentic AI systems, GenAI applications, and large-scale data platforms that real users depend on. Over 11+ years, I’ve moved from analytics to data engineering to ML productionization, and now to agentic AI architecture — combining hands-on engineering with technical leadership.

Currently at Hubbell Incorporated (Cleveland, OH), I architect multi-agent systems on LangGraph, LangChain, and CrewAI, RAG pipelines with Pinecone & Milvus, and MLOps infrastructure on AWS & Databricks. Before that, I led full-stack ML platforms at Allstate, Thomson Reuters, Cybage, and Indium Software.

I hold a Master’s in Business Analytics & Information Systems, a Bachelor’s in Electronics & Communication Engineering, and certifications across AWS, Azure, Databricks, and Python. I’m a player-coach — deep in code, but equally focused on mentorship, architectural reviews, and turning ambiguous business problems into shipped systems.

Things I’ve built & shipped.

Real production systems across five domains — not prototypes, not demos.

Agentic AI · Manufacturing

Multi-Agent Orchestration Platform

Architected a stateful multi-agent system on LangGraph with planner–executor patterns, tool use, memory, and self-validation loops — powering autonomous decomposition of complex manufacturing-ops requests.

LangGraphCrewAI MCPGPT-4o
RAG Infrastructure

Billion-Scale Vector Retrieval

Built RAG infrastructure with HNSW-indexed Pinecone & Milvus stores at billion-scale, optimized for tool-calling and JSON-mode outputs across enterprise document corpora.

Insurance · Fraud Detection

Graph-Based Fraud Engine

Engineered a real-time fraud-detection engine combining graph anomaly detection (NetworkX) with ensemble ML — surfacing duplicate-claim and staged-accident patterns that directly reduced loss-ratio exposure.
