Resume App Bug Fixes

I need an experienced next js and backend developer to iron out a handful of issues inside my résumé builder solutoon

The most urgent blocker is registration: the OTP never reaches the user, so the Firebase phone-auth flow stops before verification even begins. Once that is reliable I can move on to polishing the core résumé screen. Users must be able to open an existing résumé and freely edit its current sections; no adding or deleting is required, just clean in-place edits.

While you are in that view, please standardise typography—style, size and colour—so every heading, sub-heading and body line looks consistent across devices. Page-break logic also needs attention; long résumés should split predictably rather than clipping mid-sentence. Under the last page place a clear Download PDF button.

Finally, if the logged-in user has not upgraded to Pro, I want a prominent in-app banner that auto-routes them to the Stripe checkout page, making the upgrade path frictionless.

Deliverables
• Working OTP delivery and Firebase sign-in flow
• Editable existing résumé sections
• Unified font style, size and colour plus correct paging
• Download PDF button positioned below résumé preview
• Conditional “Go Pro” banner that redirects to Stripe

Everything is already wired up in Git; once you finish, push a clean, well-commented commit so I can verify on TestFlight.
