9 Hours to a Full SaaS: Building With Lovable From Zero to Deployed

Everyone's debating if AI can build real products.

Marcel spent 9 hours actually doing it — customer portal, Stripe payments, AI-powered document processing, file uploads, the works. Not a polished tutorial. The real build, unedited.

The key insight: prompt for systems, not features.

What you'll learn

Full customer management system Assessment workflows, client profiles, and a complete portal — built entirely through prompting Lovable.

AI-powered document processing GPT-4 Vision extracting structured data from PDFs — integrated into the app via edge functions.

Stripe payment integration via prompting No manual code. Subscription billing, checkout flows, and payment management prompted into existence.

Database design from CSV to production Starting from a spreadsheet, building production tables, file upload systems, and secure drop links.

Domain purchase to deployment in one platform The full lifecycle — from architecture planning to a live, deployed product in 9 hours.

Why this matters

Vibe coding works when you manage AI like a senior engineer manages a junior developer. Plan the architecture first, then let the tool handle implementation. This session shows the exact process — and proves what's possible when you stack AI tools systematically.
