About Me

I build AI systems
that ship to production.

I'm Lucky Patel, an AI Systems Engineer with 4+ years of full-stack development experience. I design and build production AI applications: RAG pipelines, LLM-powered products, and intelligent systems that solve real problems at scale.

As the co-founder of Mystiq Technologies, I've shipped AI integrations, chat systems, and data platforms end-to-end, from architecture to deployment. I work across the full stack: Node.js, Next.js, React, GraphQL, MongoDB, and the entire modern AI toolchain.
