Jayrr Dev

Building with AI made simple.

I have spent 7 years building modern web apps with Next.js, React and TypeScript. Most of that work is private: SaaS products, internal tools and client apps. I also teach how to build with AI for your business.

What I build

  • Private SaaS: billing, auth, dashboards and the rest of the product work
