Case Study: Building a Full-Stack Web App with Claude in Six Weeks

Project Overview
A developer without a CS degree or senior engineering experience built and shipped a full-stack web application in six weeks using Claude. The project resulted in Somnia, a dream journal with 100 users and 7 paying customers.
The Workflow
The developer treated Claude like a junior developer with unlimited patience. Every task was scoped tightly — one component, one fix, or one feature at a time. Instead of asking "build me an app," the developer provided specific prompts like "build me a dark mode editor that auto saves to Supabase every 3 seconds." The approach emphasized small scope, clear acceptance criteria, and review before merging.
Technical Stack
- Next.js 14 for the frontend framework
- Supabase for authentication and database with Row Level Security
- Tiptap for rich text editing
- next-pwa for PWA setup
- Vercel for deployment
The developer handled product decisions (what to build, why, and in what order) while Claude handled implementation.
Application Details
Somnia is a dream journal built around the insight that users have 60 seconds after waking before a dream fades completely. Key features include:
- Dark mode only interface
- Instant opening
- Auto-saving functionality
- Morning notification with countdown timer
- AI pattern recognition that surfaces recurring themes across dreams over time
The app offers a free tier and a paid Pro tier for AI insights and unlimited entries.
Key Learnings
- Tight task scope beats open-ended prompts every time
- Always review before merging — Claude is fast but the human is the product brain
- When errors occur, describe them exactly and paste the logs — Claude fixes faster than Stack Overflow
- The human in the loop does the real thinking while Claude executes
The project was built solo from Nepal with zero budget, demonstrating that current tools enable shipping real products without a team.
