NoteBill — AI-Assisted Invoice Web Application

Challenge

Turn messy notes into structured invoice data without hiding the generated output or forcing users to trust a black box.

What I built

I developed the React and TypeScript application, OpenAI-assisted structuring and rewriting, editable invoice workflows, saving, follow-up tracking, and PDF-ready output.

Outcome

The live app keeps AI-generated content reviewable and editable before an invoice is finalized, giving users a practical path from rough notes to a professional document.
