You will get a Flutter app with BLE, MQTT & IoT hardware integration
Project details
Building an IoT mobile app requires more than standard Flutter knowledge — it demands deep understanding of hardware protocols, connection resiliency, and real-time device communication.
I am a Senior Flutter Engineer with 4 years of experience specializing in BLE, MQTT, WebSockets, and Arduino hardware interfacing. I have shipped production IoT applications for UK and UAE markets — connecting mobile software directly to physical hardware devices.
What I deliver:
BLE & Classic Bluetooth device integration
MQTT protocol implementation & real-time device control
Dual-layer communication — MQTT primary, BLE offline fallback
WebSockets for real-time data streaming
Arduino & embedded hardware interfacing
Background service management & OS-level optimization
VoIP push notifications bypassing OS background limits
Live IoT app I have shipped:
DriveCard — Smart car rental app with remote vehicle lock/unlock, engine control via BLE & MQTT → Play Store
From hardware protocol design to production deployment — I handle the complete IoT mobile product lifecycle.

Skilled Flutter & Android & Ios Developer for Mobile App Development
Mounim did an excellent job on our Flutter mobile app development task. He built 3–4 clean, responsive screens for both Android and iOS and handled the API integration smoothly with proper JSON parsing and state management.
As a professional Flutter developer, he delivered well-structured, maintainable code and ensured the app was user-friendly and performance-optimized. Communication was clear, deadlines were met, and the final result matched our expectations perfectly. Highly recommended for any Flutter app project.

Senior Flutter Developer – Convert Production Web App (Firebase Backend) to Flutter (Frontend-Only)
Mounim did an excellent job as our Flutter developer, converting our web app into a clean, frontend-only Flutter app while keeping our live Firebase backend unchanged.
He smoothly integrated Firebase Auth, Firestore, and Cloud Functions, followed our fixed schema, and used Clean Architecture with Riverpod. Delivery was milestone-based, well-structured, and production-ready for both iOS and Android.
Highly recommended for any serious Flutter mobile app development project.

Web design on current woocommerce theme
I asked to do a rework on home page with content included, specified the job and everything. He simply used a template for elementor and changed few bits around. that's it and ask me how much i was willing to pay for extra content. Poor understanding of what was asked. And poor web development skills. all he does is uses templates and edits them. Anyone can do that. I'm afraid i will not recommend this individual for anyone. Complete waste of time. He did ask for what i wanted done, but it became too much for me so i had to cancel the contract. Also he never asked permissions to install extra plugins on my store.

Job Success
Bahawalpur, Pakistan - 10:50 am local time
I am a Senior Mobile Engineer with 4 years of professional experience building and shipping production-grade iOS and Android applications. I specialize in Flutter-based mobile development with a strong technical niche in IoT integration, real-time hardware communication, and high-autonomy product ownership.
Over my career, I have engineered and shipped production systems across the UK, Turkey, UAE, and Gulf markets — covering domains like ride-sharing, smart car rentals, IoT vehicle control, and logistics. I handle everything independently from initial architecture design to final App Store and Google Play deployment.
🚗 What I Build & Specialize In:
✅ IoT & Connected Hardware Apps: Deep hands-on experience implementing BLE (Bluetooth Low Energy), Classic Bluetooth, MQTT protocols, WebSockets, and Arduino hardware interfacing. I bridge the gap between mobile software and physical devices.
✅ Real-Time Mobility Systems: Advanced integration of Google Maps APIs, custom geofencing, driver-passenger synchronization, and high-performance persistent background GPS polling.
✅ Production Backend & Cloud Layers: Structuring secure authentication and dynamic real-time querying via full Firebase Suite (Firestore, Realtime DB, Cloud Functions) and Node.js.
✅ UI/UX Transformation: Pixel-perfect translation of high-fidelity Figma layout prototypes into fluid, responsive, and lightweight Flutter interfaces.
🚀 Real-World Problems I Have Solved:
🚖 Bypassing OS Background Restrictions: Standard push notifications often fail under strict mobile OS sleep limits. I engineered a custom VoIP notification architecture that bypasses iOS and Android background sleep protocols, guaranteeing time-critical driver pickup alerts and hardware alarms trigger instantly regardless of the application state.
🚗 Dual-Layer Connection Resiliency: For a smart car rental platform, connection drops can break user experience. I designed a hybrid MQTT + BLE infrastructure where MQTT handles primary commands and the application automatically falls back to offline BLE when network connectivity hits zero, ensuring uninterrupted remote vehicle control.
📉 Infrastructure Cost Optimization: Building a production app shouldn't break the bank. I maintained near-zero Firebase infrastructure overhead for a live production health application through custom synchronization logic and data pooling mechanisms, demonstrating cost-aware engineering.
⚙️ My Technical Stack:
* Languages & Frameworks: Flutter, Dart, Native Android & iOS (platform channels)
* State Management: Riverpod, BLoC, Provider, and GetX
* Architecture: Clean Architecture, MVVM, Multi-project structuring
* Protocols & IoT: BLE, Classic Bluetooth, MQTT, WebSockets, Arduino Interfacing
* Database & Cloud: Firestore, Firebase Realtime Database, Cloud Functions, PostgreSQL, Node.js
*Payments & APIs: Stripe, PayPal, Core RESTful APIs integration
📱 Shipped Production Footprint (Available on Stores):
*Smart Car Rental (IoT/BLE): Remote vehicle hardware control platform utilizing hybrid data pipelines.
*Ride-Sharing (Real-Time Location): High-frequency live tracking and driver dispatch mobility network.
*Driver Dispatch Ecosystem: Fleet management, dynamic routing, and background sync platform.
I don't just write code — I own the product lifecycle. I proactively communicate throughout the process, structure maintainable systems, and collaborate easily with your backend teams on API design.
