I will build your fullstack ai saas mvp with nextjs openai and stripe billing
Marcos
About this gig
Ship a real, revenue-ready AI product, not a demo that collects dust.
Anyone can generate a pretty landing page now. Almost nobody can wire the auth, the database, the billing, and the AI layer into something that survives its first hundred users.
I built CraftGent: a GenAI SaaS serving 1,000+ users across 700+ businesses, processing 100,000+ messages a month on live Stripe billing. And JuliaBot: a multi-agent platform with 500+ users, Stripe subscriptions, Docker and Kubernetes.
WHAT YOU GET
A live product on your domain, taking payments on day one
User accounts, dashboard, database, Stripe subscriptions wired end to end
Full source code and repo ownership. No lock-in, no licence fees
STACK
Next.js, React, NestJS / Node.js, PostgreSQL / MongoDB, OpenAI / Claude / Gemini, Stripe, Clerk, Docker, GitHub Actions
HOW WE WORK
Delivery runs in milestones, so you see and approve working software at each stage instead of waiting weeks for one big reveal.
Message me before ordering with your idea. I will come back with a proposed v1 scope, an architecture, and an honest opinion on what to cut. Most MVPs fail from building too much.

I build production software that ships: full-stack web, cross-platform mobile, and AI systems running in front of real users.
Recent work includes a yacht management platform handling 50,000+ API requests daily, a GenAI chatbot SaaS serving 700+ businesses, and Play Store apps with 99%+ crash-free sessions.
Stack: React, Next.js, Node.js, NestJS, TypeScript, React Native, Python, Go, PostgreSQL, LangChain.
Tell me the problem, not the ticket. I'll scope it, build it, and ship it.

FAQ
Do I Own the Code?
Completely. Full source code, repository access and deployment credentials transfer to you on delivery, with no licence fees and no dependency on me afterwards. You can hire any developer to continue the work. I write it to be handed over.
Can you take a rough idea and scope the MVP?
That's usually the most valuable part of the engagement. Send me the idea and I'll come back with a proposed v1 feature set, an architecture, and an honest view of what to cut. Most first versions fail from doing too much, so my job is to find the smallest build that proves people will pay.
Do you handle deployment and payments?
Yes, both. Your app ships live on a real domain with SSL, and Stripe subscription billing is wired end to end, including webhooks, plan upgrades, failed payments and the customer portal. I've built and operated billing on live products, so you launch able to take money on day one.
Can you add to or fix an existing codebase?
Yes. I work in existing repositories regularly, including projects started with AI coding tools that stalled once they hit real users. Share the repo and I'll review it and tell you whether to extend or rebuild before you commit to either.
