AI-assisted development

Over the past few months I’ve been experimenting with AI-assisted development and managed to ship the following:

• 840 unit tests (going from almost zero to ~97% coverage)
• 6 end-to-end test suites with Playwright
• i18n across the app (English + Portuguese)
• Major framework upgrades (Next.js 16, Tailwind 4, Clerk 6)
• CI pipeline with GitHub Actions running automated tests
• Performance improvements

Pretty impressed by how much I was able to ship in a short period of time.
