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.
