Nadimullah Khan AI and Blockchain Engineer

About

Building the intersection of AI agents and decentralized systems.

I am a senior engineer with over 20 years building scalable digital systems, now focused on the convergence of agentic AI and multi-chain blockchain infrastructure.

I design and deliver production-grade GenAI systems: LLM-based agents, multi-agent orchestration layers, RAG pipelines, and automated decision engines integrated with real-time data streams. On the blockchain side, I architect multi-chain platforms across EVM and non-EVM networks, smart contract systems, DeFi protocol integration, and secure off-chain orchestration.

Currently leading Graphixcon — a technical consultancy building AI-driven automation systems and blockchain platforms for clients worldwide.

Note: Most projects are under NDA. The above is a generalized overview — happy to discuss specifics on a call.
