    I’m getting ready to broadcast a mobile-based gaming session live on YouTube and want everything to look and sound professional from the first second on-air. I’ll be running the show through Streamlabs, so what I need now is an experienced hand that can fine-tune the app, design tidy overlays, balance audio, and walk me through the optimal settings for a phone-captured feed. The workflow I’m picturing is simple: we hop on a call, you remotely guide me while I screen-share, we build the scenes together, add the alert boxes, test bitrate and resolution, and then run a short private test stream to be sure the chat, notifications, and capture are rock solid before launch. If anything glitches, I’d like quick troubleshooting advice so I can fix it on the spot during fut...

    I’m commissioning a full, production-ready ride-sharing solution that covers both sides of the marketplace. The scope spans native iOS and Android rider apps, a mirror set of driver apps, plus the server stack that powers real-time matching, payments, and dashboards. Core workflow • Riders open the app, watch nearby drivers update live on a map, request a trip, and pay securely with a credit or debit card. • Drivers toggle their availability, receive requests, navigate via in-app GPS, then review completed trips and earnings. • The backend matches riders to drivers instantly, calculates distance-based fares, and settles transactions to the appropriate accounts. Key components to build • Two mobile apps (Swift/SwiftUI for iOS, Kotlin/Jetpack for Android) ...

    I’m turning the first version of my mobile product into reality and need one dependable developer to own the build and guide the technical choices along the way. We’ll work in FlutterFlow or Bubble—whichever you believe will get us to market fastest—on top of a Firebase backend. I’ll handle product direction; you’ll handle code and architecture. Clean functionality is the goal, not pixel-perfect polish. The MVP must launch with: • User profiles (avatar, basic settings) • Real-time messaging between users • A content-sharing area (text, images, short video) The UI style should feel modern and colourful while remaining intuitive.

    I’m planning to launch a simple yet solid music-streaming application that runs natively on both Android and iOS. The core focus is a clean audio player that fetches and streams tracks from my back-end, with social-media login (Google, Facebook, or Apple) as the only authentication option—no email/password flow needed. I’m flexible on the tech stack: if you favour Flutter, React Native, Kotlin Multiplatform, or native Swift + Kotlin, that’s fine as long as the end result feels fast, modern, and stable on each platform. UI/UX assets, API endpoints, and sample tracks will be provided.

    I’m ready to commission the first release of a security-focused mobile application, launching on iOS before we expand to Android. The core of the product is continuous GPS tracking that must keep running in the background without draining the battery or being shut down by the OS. To protect sensitive medical data every byte stored on-device has to be encrypted and locked behind biometric authentication (Touch ID / Face ID) with an optional 4- to 8-digit passcode fallback.

    I need a skilled Flutter developer to plug a very specific feature set into my existing kids-focused mobile app. The task is all on the client side: build AR camera filters that work with ARCore on Android and ARKit on iOS, track individual eye movements in real time, and capture short videos at defined moments, then push those clips to a REST endpoint that is already live and documented. You will wire up the camera feed, layer the AR assets, implement per-eye tracking accuracy (not just general face gestures), trigger recording when my code tells you to, and send the resulting MP4 to the backend with the required headers and auth token.

    I have an iPhone 12 pro max running iOS 26.2 that is stuck on the activation lock screen.
