AI Vibecoding Hackathon: My Claude Code Experiment 🤖

Last weekend I attended an AI Vibecoding Hackathon with a twist - all vibes, no traditional coding required. I used this as the perfect opportunity to push Claude Code to its limits and see what fully automated AI development could achieve.

My mission: Build a Go-powered LLM middleware app with a React frontend. The catch? I don't actually know Go. 😅

The 4-Step Journey:

Step 1: Project Setup (10 minutes)

Set up the repository structure for a Go backend + React frontend combo

Step 2: Strategic Planning with Claude Code (20 minutes)

- Asked Claude to generate a medium-level task breakdown

- For each task, requested detailed low-level checklists with testing criteria

- Created a master high-level design document linking everything together

- This upfront planning proved crucial for autonomous execution

Step 3: The Autonomous Coding Marathon (6 hours)

Activated Claude Code Plan Mode with the instruction: "Review high-level.md, work through each linked low-level design, create and execute a plan to complete every checklist item autonomously."

Then I hit approve and watched the magic (and chaos) unfold.

Step 4: Vibe Coding Reality Check (12+ hours)

Results: ~80% accuracy (finger-in-the-air estimate). Claude Code delivered a working foundation but left me in "vibe coding hell" untangling some... creative architectural decisions using Cursor and manual debugging.

Key Takeaways:

- AI coding tools are incredibly powerful for bootstrapping projects in unfamiliar languages

- Detailed upfront planning dramatically improves autonomous AI performance

- The 80/20 rule applies - AI handles the heavy lifting, humans polish the details

- "Vibe coding" is real, and it's both frustrating and oddly satisfying

The future of development is definitely human-AI collaboration, not replacement. Claude Code got me 80% of the way there in a language I've never touched - that's pretty remarkable.

Huge thanks to Encode Club for hosting the AI Vibe Code Hackathon - what an amazing event! Also grateful to all the judges and speakers who made this such a valuable experience.

Anyone else experimenting with AI-first development workflows? Would love to hear your experiences!
