React/Base44 Developer — Bug Fixes + iOS Paywall

Looking for a developer to handle a scoped set of fixes on my iOS app, built on Base44 (a no-code platform) and exported to React/Vite, currently live on TestFlight. Work includes: two reliability fixes in the AI plan-generation flow, two small UI polish items (button color, onboarding progress bar), verifying legal policy links are reachable in-app, replacing a Tailwind CDN script with a proper production build, and implementing a paywall (one free use, then a subscription) via Apple's In-App Purchase/StoreKit, including App Store Connect setup. Ideal candidate has React experience, familiarity with Base44 or similar no-code export platforms, and prior hands-on experience shipping an iOS subscription with StoreKit. Budget is $650 fixed-price for the full scope; slight flexibility for the right candidate.
