I tried running Qwen 2.5 Coder locally and accidentally built a full MERN stack app in 1 hour

Was trying to run Qwen 2.5 Coder offline on my laptop but ended up
building this full MERN stack project management app with 2FA using
Haiku 4.5 in one evening.

Here's exactly what I built and how:

What I built

A full ProjectHub app with:

  • Beautiful glassmorphism dark UI
  • JWT Authentication with 2FA (Google Authenticator)
  • Dashboard with project stats
  • MERN stack (MongoDB, Express, React, Node.js)
  • Vite + Tailwind CSS frontend

My setup (all free, ₹0)

  • Ollama — runs AI models locally on my laptop
  • Qwen 2.5 Coder 14B — local offline coding model
  • Claude Haiku 4.5 — via GitHub Copilot free access
  • Continue.dev — free Copilot alternative in VS Code

How it happened

  1. Started by installing Ollama to run Qwen locally
  2. Set up Continue.dev in VS Code
  3. Haiku 4.5 auto-detected through GitHub Copilot
  4. Gave it one detailed prompt for the full MERN stack
  5. It created 20+ files automatically in minutes
  6. Fixed static buttons and connected the backend
  7. Added 2FA with Google Authenticator

The prompt that started everything

Build a full MERN stack project management app with:
- JWT auth + 2FA
- Glassmorphism dark UI
- Dashboard with stats
- Framer Motion animations
- Tailwind CSS
Create ALL files with complete working code.
Enter fullscreen mode Exit fullscreen mode

Time taken

⏰ Total: ~2.5 hours from zero to working app with 2FA

Key takeaway

AI doesn't replace developers — it makes you 10x faster.
I still had to:

  • Know what to ask for
  • Fix bugs and connect everything
  • Understand the code it wrote
  • Make design decisions

The AI typed fast. I built the product.

Claude rocks anyways 🔥
