Senior Full-Stack Developer (React Native/Next.js) for Final App Polishing & Deployment for 2 apps

I have two applications—a video-centric mobile platform and a complex document processing tool—that are 99% functionally complete.

I am looking for a Senior Developer to act as a "finisher" to audit the code, resolve remaining logic bugs, and manage the final deployment to the app stores. ​Key Deliverables: ​Mobile Platform (React Native/Expo): Fix minor UI/UX inconsistencies, resolve a hang on the media upload page, and optimize real-time communication stability. ​Document Tool (Next.js/Node.js): Perform a final logic audit on a sophisticated formatting engine to ensure strict adherence to industry-standard styles. ​Infrastructure: Verify Stripe webhook functionality for tiered subscriptions and finalize the PostgreSQL (Neon) database synchronization. ​Launch: Manage the full end-to-end deployment process for iOS (App Store Connect) and Android (Google Play Console). ​Technical Stack: ​Frontend: React Native (Expo), Next.js, Framer Motion ​Backend: Node.js, PostgreSQL (Neon) ​APIs: Daily.co (WebRTC), Stripe, Uploadcare ​Environment: Replit / GitHub ​Candidate Profile: I need a "finisher" who is comfortable jumping into existing codebases.

You should have a proven track record of resolving structural UI collapses, optimizing media-heavy mobile flows, and successfully launching apps on both major stores.
