I will build a secure ai saas mvp with nextjs, stripe and openai


About this gig
An AI demo takes a weekend. An AI SaaS that survives real users takes engineering: secure auth, working payments, and AI costs that can't spiral. That's what I build.
I'm a full-stack AI developer shipping SaaS MVPs and web apps with Next.js, React, Node.js, Supabase and OpenAI, from first scope to live product.
Recent work:
- Fintech SaaS with Stripe subscriptions, Plaid bank sync, multi-channel alerts and an AI advisor
- All OWASP security findings fixed on a fintech app
- 98+/100 Google Lighthouse scores in production
What I build:
- AI features: ChatGPT and OpenAI integration, chatbots, AI agents, chat-with-your-docs (RAG)
- SaaS core: auth, database, Stripe billing, admin dashboard, multi-tenant teams
- Prototype to production: harden a Lovable, Bolt or Cursor app
How it works:
1. Send your idea. Get a free build plan and a fixed quote.
2. Milestone delivery with a live preview link after each one.
3. Deployed app, setup docs and full source code. 100% yours.
Every build: TypeScript, API keys kept server-side, rate limits on AI calls. No templates.
Message me before ordering with a few lines about your idea.

FAQ
Do you build the app with AI features like ChatGPT/OpenAI?
Yes. I integrate OpenAI, custom AI agents, and intelligent automation directly into your SaaS from AI chat to data processing and lead scoring. Tell me your use case and I'll recommend the right approach.
What tech stack do you use?
Next.js, React, and TypeScript on the front end; Supabase, Node.js, and PostgreSQL on the back end; Stripe for payments. I choose the stack that fits your project, not a one-size-fits-all template.
I have a half-built or "vibe-coded" app (Lovable, Cursor, Bolt). Can you finish/fix it?
Absolutely. I regularly take vibe-coded apps and make them production-ready fixing auth, APIs, security, and deployment. Send me the repo or link and I'll assess it.
Will I own the code?
100%. You get full source code and ownership on delivery, deployed wherever you want.
Can you handle payments and user accounts?
Yes secure authentication and Stripe payment integration are included from the Standard package up.
Why should I message before ordering?
SaaS projects vary a lot in scope. A 2-minute chat lets me scope it accurately, recommend the right package, and avoid surprises so you get exactly what you need.
Which package should I choose?
Basic adds one AI feature, as a small live tool or inside your current app. Standard is a full MVP with accounts, payments and AI. Premium is a launch-ready SaaS with teams, admin, security hardening and support. Unsure? Message me your idea and I'll recommend one.
Can you finish my Lovable, Bolt, Cursor or v0 app?
Yes. I audit the code, move API keys server-side, fix auth and Supabase row-level security, clean up the architecture and deploy it properly. Share the repo or project link in chat for a fixed quote.
Who pays for OpenAI, hosting and database costs?
You pay the providers directly. OpenAI, Supabase, Vercel and Stripe accounts are created in your name, so you own the data and the billing. I add rate limits and usage caps so AI costs stay predictable.
