I'm Abhishek, an AI Engineer building production-grade RAG and agentic AI systems for enterprise clients. I currently work on-site with one of India's largest industrial conglomerates, where I lead end-to-end delivery — from architecture and prompt engineering to client demos and stakeholder management — across a portfolio of live AI projects. My focus is on the practical side of LLM engineering: RAG pipelines, multi-agent architectures, LangGraph, secure tool execution, and prompt systems that actually hold up in production (not just in a demo). I write about agentic AI architecture on LinkedIn and Substack — covering things like design patterns for agents, Model Context Protocol, and defense-in-depth security for AI systems. If you're building or scaling an AI product and want a second pair of eyes on your architecture, prompt design, or RAG strategy — or you're prepping for an AI engineering interview and want someone who's been on both sides of the table — I'm happy to help.
