About this gig

Have an AI SaaS idea but no working product yet? I build AI SaaS applications from scratch authentication, subscription billing, and the AI engine itself, working together as a real product, not a prototype.


I'm a full stack developer who develops AI SaaS platforms end-to-end using Next.js, React, Node.js, MongoDB/PostgreSQL, and OpenAI/Claude API integration. I think through scope like a co-founder would if a feature isn't needed for your MVP, I'll say so instead of padding the invoice.


What I deliver:


  • Multi-tenant SaaS architecture
  • User authentication & role-based access
  • Stripe subscription billing (trials, plans, usage-based pricing)
  • Core AI feature built with OpenAI / Claude / LangChain
  • Admin dashboard and deployment


Tech stack: Next.js, React, Node.js, Express, MongoDB, PostgreSQL, OpenAI API, Claude API, LangChain, Stripe, Tailwind CSS.


I work directly with founders, not through a team of subcontractors. Most of my SaaS clients move into an ongoing retainer once their MVP is live, because the real work starts after launch.


Message me your SaaS idea before ordering even a rough one-paragraph description is enough for me to map your real MVP scope and timeline.
