Full-Stack AI Developer for SaaS MVP

We are building a SaaS product called Wren AI that helps small businesses create high-performing Facebook ad creatives using AI.

Users describe their business and campaign goals, and the platform generates ad images, headlines, and text automatically.

We want to build an MVP with:
✔ user signup/login
✔ input form
✔ AI-generated creatives
✔ download option
✔ simple dashboard

Tech Stack preference:
✔ Azure OpenAI / Stable Diffusion
✔ React or Next.js frontend
✔ Node.js / Python backend
✔ scalable + low-cost

You must:
✔ have built AI SaaS before
✔ deliver clean documented code
✔ deploy to Azure
✔ help set up billing protection + alerts
✔ communicate clearly
