The Solo Developer AI Automation Stack: Code Once, Automate Everything

As a solo developer, the biggest time sink isn't code — it's repetitive tasks. Writing blog posts, managing deployments, handling PRs... Automate these and you can focus purely on building.

Here's my full automation stack:

1. Auto-Generated Build Logs

git push → husky pre-push hook → Claude CLI → markdown build log

Every time I push code, Claude analyzes the commit diff and generates a bilingual (Korean/English) build log. I develop, and blog content accumulates automatically.

2. Auto PR + Merge

# .github/workflows/auto-merge-claude.yml
on:
  push:
    branches: ['claude/**']
jobs:
  auto-merge:
    # Creates PR → squash merges → deletes branch

Any branch Claude Code creates gets automatically merged to main. Zero manual PR management.

3. Daily Auto-Rebuild

// vercel.json
{ "crons": [{ "path": "/api/revalidate", "schedule": "0 6 * * *" }] }

Write on dev.to → next morning it's automatically on my portfolio site.

4. Portfolio Auto-Sync

Drop a .portfolio.yaml in any GitHub repo:

title: My Project
status: 운영중
stack: [Next.js, Stripe]
one_liner: AI-powered fortune telling

The portfolio site fetches and displays it automatically.

The Core Principle

If you've done it manually twice, automate it.

The time invested in automation pays back within days. And with AI tools, building the automation itself is fast.

Total setup time: ~2 hours. Time saved per week: ~5+ hours. The math is obvious.
