I will build your ai saas mvp with next js and fastapi


About this gig
You have an AI product idea. I build the AI SaaS MVP - a real application with auth, a real database, and billing, not a demo that collapses at ten users.
I've shipped exactly this in production: 600+ commits as one of five core engineers on a live AI platform built with FastAPI and Next.js, plus a deployed emergency-transport product and a multi-agent AI diagnostic system of my own.
WHAT YOU GET
- Next.js (React) frontend and FastAPI or Node.js backend, PostgreSQL database
- Your core AI feature on the right model for your budget (OpenAI, Anthropic, or Groq)
- Authentication, user roles, and Stripe billing if you need revenue on day one
- Docker deployment so your MVP runs somewhere real, not just my laptop
- Clean, documented code your next engineering hire can actually pick up
WHY ME
I scope honestly before we start. If your idea is bigger than one package, I'll say so upfront and break it into phased milestones - no half-built features, no scope-creep invoices.
Message me your idea and I'll send back a realistic scope, timeline, and what I'd cut from v1 to get you launched faster.

FAQ
What if my AI SaaS MVP is bigger than these packages?
Message me first and we'll scope it into phased milestones with fixed prices per phase. You'll always know what you're paying for before it starts.
I'm non-technical. Can you still work with me?
Yes — most of my SaaS clients are. Describe the product in plain English and I'll translate it into a technical scope and tell you what to cut from v1.
Which LLM should my product use?
Depends on volume, latency, and budget. Groq is free-tier friendly for early MVPs; OpenAI and Anthropic are stronger for complex reasoning. I'll recommend based on your case, not my convenience.
Do you handle payments and subscriptions?
Yes — Stripe subscription or usage-based billing is included in Standard and Premium.
Who owns the code and can another developer take over?
You own everything. The code is documented and conventionally structured specifically so your next hire can pick it up without me.
