Flutter LED App Development Muhammad has been a great partner in building the first version of the Medalite app. He handled a fairly complex project involving Flutter development, BLE communication with hardware, and custom light sequencing features, and was able to bring it all together into a working product.
He’s reliable, communicates clearly, and is open to feedback and iteration, which was especially important as the scope evolved. I appreciated his willingness to work through technical challenges and adjust based on changing requirements.
Like any complex build, there were moments where we had to clarify direction or refine implementation details, but overall he stayed committed and worked through issues professionally.
I’d recommend Muhammad to anyone looking for a solid developer for mobile apps, especially projects that involve hardware integration or custom functionality.

Senior Full-Stack Developer (React Native/Next.js) for Final App Polishing & Deployment for 2 apps There is someone for everyone, from newbies to pros, and i believe Muhammad is for both. Muhammad was professional, straightforward and considerate when conducting my audits. Although we were not able to come to an accord on pricing, he was very understanding and attempted to accommodate me as best he could. I would highly recommend communicating with him to see if he is a fit for you.

✅ Upwork Top Rated Plus & Verified Mobile App Developer

AI-Powered React Native & Flutter Developer | BLE Hardware + LLM Integration Specialist

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, and a Top Rated Plus track record that speaks for itself.

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.
