We are looking to do a new build of our patch bay label designer tool. Customers are currently able to pick their model of patch bay, add text labels, colorize, and group. They can then checkout and it creates print ready artwork for our team to produce. The UI is a bit clunky and there are some features we want to add such as an admin tool to add and edit labels. You can see the current tool here: https://create.traceaudio.com/

Mobile app for continuous searching. Enter a query in the search box powered by AI to sharpen up the requst, chose the duration of the search using pop up calendars. Hit submit, the app will continuously search for new information starting ONLY from the start date to the end date. When a new query is found, the app notifies and displays the web link to be clicked on and reviewed. Once the link has been viewed, the link goes from green to red to represent the link has been view and the customer now can delete that notification. The notification includes a time date stamp when the notification was found. Possibly to use AI in the search box to articulate the request being searched. This is a continuous notification app. The customer will have up to 10 queries and 10 notifications per query. The app has to be compatible for Android and IOS. As far as security, there is no information to steal, the customer only needs to creat a login and password, no personal information collected no billing. Billing is handled by the Playstore and Apple store. The app will be subscription based based on the frequency of the search. Ex: search frequency every hour, or search frequency every 5 minutes.

I need an experienced developer to migrate an existing Base44 (React + Vite) prototype to production-grade native mobile apps for both iOS (App Store) and Android (Google Play), with architecture built to scale. Scope of work: Export and thoroughly audit the Base44 codebase. Migrate frontend to production React Native (Expo strongly preferred) for iOS and Android. Migrate backend logic to a scalable solution (e.g. Supabase or equivalent). Implement and rigorously test permissions, privacy requirements, and store compliance for both platforms. Verify, harden, and optimize all API integrations. Battle-test features, edge cases, and performance across iOS and Android devices. Prepare full submission readiness for Apple App Store and Google Play. Provide architecture guidance for scaling to high user volumes. Must-haves: Multiple live React Native apps successfully published to both the Apple App Store and Google Play (provide links). Experience migrating from no-code/AI-generated or web codebases to cross-platform native. Strong backend experience with scalable solutions (Supabase, Firebase, Postgres, etc.). Deep expertise in mobile permissions, privacy compliance, and the full submission/review processes for both iOS and Android. Excellent code quality with TypeScript, modern React Native patterns, state management, and navigation. Portfolio + GitHub examples required. References from previous production mobile projects a big plus. Strong communication for phased collaboration with clear milestones. Engagement: Phased project (Audit & Plan → Migration → Polish & Testing → Launch Prep). Available ASAP. Remote OK with preference for EST/overlapping hours. Florida-based a plus but not required. To apply: Email/DM [your email] with: App Store and Google Play links + relevant GitHub/portfolio Brief summary of relevant migration or scaling experience High-level proposed approach Availability ASAP

Please see product brief of the application I'm looking to build. I can create mock ups. Note that I am looking to create the earliest stage MVP so that I can test in field as soon as possible.

We're looking for a senior mobile engineer with real native iOS and Android depth to build the mobile experience for a secure healthcare app. The mobile app is the main product, and the standout features — Apple Wallet passes, home-screen widgets, Live Activity / Dynamic Island — are native OS extensions that can't be built in JavaScript. This is not a "React dev who also does some mobile"; it's a real mobile engineer. The app serves healthcare field representatives who need secure mobile workflows for managing documents, credentials, status visibility, and access in the field. What you'll own: - Web: React + TypeScript, working against an API client generated from the backend so the two never drift - Mobile (cross-platform): React Native + Expo for shared app UI and logic - Mobile (native): the real differentiators — Apple Wallet passes (PassKit), home-screen widgets (WidgetKit), Live Activity / Dynamic Island (ActivityKit) — native iOS (Swift) and Android (Kotlin) - On-device security: storing credentials safely with platform secure storage (Keychain/Secure Enclave on iOS, Keystore/StrongBox on Android) Must have: - React and TypeScript (modern hooks, a server-cache library like TanStack Query) - React Native and Expo, ideally on the current New Architecture - Real native iOS (Swift) and Android (Kotlin) experience, not just JS wrappers - App Store / TestFlight / Play Console release experience - On-device secure storage (Keychain/Keystore) awareness Strongly preferred: - Apple platform extensions: PassKit, WidgetKit, ActivityKit (Live Activity) - Working against a generated / contract-driven API client - Monorepo and shared-package experience - Front-end testing discipline

I’m looking for a skilled app developer to help create a clean, modern, and fully functional mobile app from start to finish. The app needs to look professional, be easy to use, and work smoothly.
