Everyone — a free public tool, and proof I can ship a real product end to end

The problem

Freelancers and small sellers shouldn't need a paid subscription to send a clean, professional invoice.

Most free tools wall the basics behind sign-up — Bruno starts from a blank invoice you can print immediately.

What I built

A complete product, not a demo — invoice editor with print-ready output, optional accounts with cloud sync, reusable clients/projects/identities, a budget tracker, and an admin panel.

  • No-signup invoicing: type, print, done — drafts survive locally
  • Supabase backend with row-level security proven by a 70-test boundary suite
  • Captcha + rate limiting on every public entry point
  • Integer-cents money math with currency-aware rounding

The outcome

Live and open to the public, secured with row-level security, captcha, and rate limiting.

a real product with real users
