I’m looking for a developer who can build a small, reliable tool that logs into my personal Gmail account and harvests only the subject lines from selected messages. Here’s what I need the application to do: • Authenticate securely with Gmail (OAuth 2.0 preferred, IMAP fallback is fine). • Let me choose the folder/label or a simple date range to target. • Pull every subject line in that scope, nothing else—no bodies, no sender addresses. • Export the results to CSV or JSON in a single click. • Run on Windows or in a lightweight web dashboard; whichever you find faster to ship is fine, provided setup is straightforward. I don’t need a full-featured mailbox crawler—just a focused, clean extractor that respects Gmail API quotas and is easy for a non-technical user to operate. If you can wrap it in Python, Node.js, or any language you’re comfortable with and document the short setup steps, that works for me. Please outline your chosen tech stack and rough timeline when you reply.
