Flutter Developer (iOS & Android) – Strong UI, BLE & Realtime Hi, We’re looking for an experienced Flutter developer to help us build a high-quality mobile app (iOS & Android) for a connected hardware product. This is not a generic app. The project involves real-time interaction with a physical device, a strong focus on UI quality, and support for remote control with video and audio. What you’ll be working on A Flutter app for iOS and Android Implementing pixel-accurate UI from our mockups (Figma) Bluetooth Low Energy (BLE) communication with a custom device Real-time control features Remote interaction using video and audio (WebRTC or similar) Polishing animations, transitions, and overall UX UI matters a lot here We already have mockups and a clear design direction. Your job is to turn those mockups into a polished, production-ready app. Attention to detail is important: spacing typography animations responsiveness across devices If you mainly focus on backend or logic and are not comfortable with UI work, this is probably not the right project. What we’re looking for Solid experience with Flutter (real production apps) Strong ability to implement UI from Figma accurately Experience with BLE integration in mobile apps Experience with real-time video/audio is a big plus Comfortable working independently and communicating clearly Nice to have (but not required) Previous work with hardware-connected apps WebRTC experience Experience with performance-sensitive or real-time apps Project details Freelance / contract Fully remote Initial scope: ~3 months (MVP) Possibility of long-term collaboration if things go well How to apply Please send: Links to apps you’ve built (App Store / Google Play) Screenshots or short videos showing UI quality A brief explanation of your experience with Flutter and similar projects Your availability and estimated timeline If you enjoy working on high-quality UI, real-time features, and non-trivial mobile apps, we’d love to hear from you.

Hi Ricardo, I’ve read your Real-Time Flutter + BLE project and I’m confident I can deliver a production-ready MVP for iOS and Android with a pixel-perfect UI from your Figma, robust BLE, and real-time video/audio. I’ve built production Flutter apps with BLE integration, responsive UI, and media streaming. My approach: convert your mockups into a precise, high-quality UI; implement stable BLE communication with clean state management and robust reconnect logic; add real-time controls and latency-conscious syncing; integrate video/audio with WebRTC or a similar stack; polish animations and transitions for a premium UX; and ship with solid tests, performance tuning, and clear docs. I’ll work remotely, communicate clearly, and align with your ~3-month MVP schedule, delivering visible milestones and regular updates. If you want to discuss details, I can start with a kickoff today and share a lightweight prototype within the first two weeks. What are the exact BLE services and characteristics for the device, and any special pairing flow? Do you have preferred Flutter BLE plugins (flutter_blue, flutter_reactive_ble) or a custom plugin? Which WebRTC setup do you want (server-based vs peer-to-peer) and do you have STUN/TURN servers? How should remote control commands be authenticated and secured? What latency targets do you expect for real-time control and video? What architecture and state management do you prefer for the app (Bloc, Riverpod, MVVM, etc.)? Do you have a prefer

Hi Ricardo, this is Elias from Miami. I went through the description carefully. This is clearly not a “basic Flutter app” — it’s a UI-heavy, real-time product tied to hardware, and that’s exactly the kind of work I focus on. I’ve built production Flutter apps for iOS and Android where UI quality mattered just as much as logic. I’m very comfortable translating Figma into pixel-accurate layouts, handling spacing, typography, animations, and making sure everything feels smooth and intentional across devices. I don’t treat UI as an afterthought. On the technical side, I’ve worked with BLE for custom devices (state sync, commands, reconnect logic, edge cases) and with real-time features where latency and reliability matter. A few project-specific questions so I’m fully aligned: Q1: For BLE, is the protocol already defined (characteristics/commands), or will part of the work involve shaping the interaction layer as we go? Q2: For remote video/audio, is this peer-to-peer (direct device ↔ app) or brokered through your backend/services? Q3: On the UI side, are animations fully specified in Figma, or do you expect some motion/transition decisions to be handled during implementation? Happy to share relevant app links and UI examples once we connect. Looking forward to discussing the MVP scope and timeline. Best, Elias
