I shipped a SaaS with zero CS degree — here's my stack

18 months ago I couldn't read a stack trace. Last week I hit $400 MRR on my first product. **What I built:** A niche invoicing tool for freelance video editors. **My stack (chosen because Claude knows it well):** - Next.js App Router - Supabase (auth + db) - Stripe - Vercel **The honest truth about vibe coding:** - 60% of the code was AI-written - 30% was me editing AI code - 10% was me actually understanding what I typed The 10% matters more than the 90%. You still need to debug, deploy, and handle angry users.
