Full-stack web developer & AI engineer for product teams

I build production-ready apps with Next.js, React, and Node.js while shipping AI agents and automations that plug into sales, ops, and support. Teams bring me in when they need one builder to own the stack, connect data, and launch real AI tools without slowing the roadmap.
