AI Full Stack Engineer | Mobile App Developer | React Native & Flutter | BLE & IoT | LLM Integration | ML
Most mobile apps fail not because of bad code but because the developer couldn't handle what came after the screens. BLE sync breaks. The AI feature needs to talk to real hardware. The App Store review gets rejected. That's exactly the gap I've built my career around closing.
I'm Muhammad. 7 years building production mobile apps, $100K+ earned across 38 contracts on Upwork.
WHAT I ACTUALLY BUILD:
✅ React Native apps, from blank repo to App Store, end-to-end
✅ Flutter apps with BLE/NFC hardware integration (custom protocols, firmware handshake, real-time sync)
✅ AI-powered mobile features with OpenAI, Claude, Gemini APIs wired directly into native UX (not bolted on top)
✅ LLM + RAG pipelines built into mobile, not web wrappers
✅ Node.js backends designed for mobile clients
✅ Native iOS (Swift) when cross-platform is the wrong call
SHIPPED & VERIFIED:
• Medalite: Flutter app with custom BLE light therapy mask. Real-time hardware sync, firmware handshake. $12,300. ⭐ 5 stars.
• Chaser: Long-term React Native engagement platform. $21K+. Client kept building.
• iOS Teleprompter App: High-complexity Swift + React Native, real-time text rendering. $6,500. ⭐ 5 stars.
• AI Analytics for iOS: LLM-powered insights wired into a native iOS app. 135 hours. ⭐ 5 stars.
• Audio App MVP: Full Flutter build. Client returned for more.
Industries: Healthcare · Fitness · Fintech · IoT · AI/ML
I respond within 10 to 15 minutes. I don't ghost milestones.
If the scope is clear, send it and I'll give you a number.
If it's complex, I'll ask the right questions and we'll figure it out together.
