## Headline

GenAI & Agentic AI Engineer \| LLMs · RAG · LangChain \| Building Production AI Systems on GCP & AWS

## About

I build production GenAI systems — not demos\. Over years across Intel, TCS, and now Tensaw Technologies, I've worked across the full AI stack: from silicon\-level validation at Intel \(where I developed a sharp instinct for systems reliability and debugging at scale\) to shipping agentic AI applications and LLM\-powered pipelines in production\. What I work with: — LLM Orchestration: LangChain, LangGraph, Agentic AI frameworks — RAG Pipelines: retrieval\-augmented generation, vector databases, semantic search — Models: Gemini \(Vertex AI\), OpenAI, open\-source LLMs via HuggingFace — Deployment: FastAPI · MLflow · Docker · AWS · GCP — Vision & OCR: Computer Vision pipelines for document and image understanding — Languages: Python · SQL · Shell Domains I've shipped in: Computer Vision \| NLP \| Agentic AI \| OCR \| Deep Learning \| Generative AI I also published research on ML\-based agricultural disease detection — an early signal of where I was headed\. Currently at Tensaw Technologies \(Kochi\) as an Associate ML Engineer, building and deploying AI solutions for real business problems\.
