🏆 TOP RATED | Top 10% on Upwork | 100% Job Success | 15 Projects Delivered Most Flutter developers have never connected an app to physical hardware. Most IoT engineers can't ship a polished cross-platform product. Almost none of them are wiring AI agents into either. I work at that intersection — and it's where the hardest, most valuable problems live. I'm Mohamed, a Flutter and IoT engineer with 4+ years building production mobile apps, connected device systems, and AI-powered products for startups and businesses across Europe and the US. I own the full stack: Flutter UI, native platform integrations, Firebase/Supabase backends, IoT protocols, and LLM/AI agent layers. I also built and shipped CertifyCrafter — a live B2B SaaS product — solo. So I know what it takes to own a product, not just contribute to one. ━━━━━━━━━━━━━━━━━━━━━━━ WHAT I BUILD ━━━━━━━━━━━━━━━━━━━━━━━ ✅ Flutter apps with deep native hardware integration (BLE, MQTT, platform channels) ✅ AI agents and LLM-powered features inside real mobile products ✅ End-to-end IoT systems: device communication → mobile app → cloud backend ✅ Cross-platform mobile apps (iOS & Android) with Firebase/Supabase ✅ Internal business tools, dashboards, and workflow automation ✅ Full SaaS MVPs from concept to production deployment ✅ OpenAI & LLM integrations (RAG, function-calling, agents) ✅ API design and third-party integrations ━━━━━━━━━━━━━━━━━━━━━━━ RECENT CLIENT FEEDBACK ━━━━━━━━━━━━━━━━━━━━━━━ ⭐ "He was proactive and able to deal with tasks that were not 100% defined yet. He was quick but still brought great code quality. The few times when I thought he had forgotten something, it turned out it was done deliberately and with a purpose. I can highly recommend working with him." — German Medical University (Flutter + Supabase project) ⭐ "Mohamed was an excellent freelancer, showcasing professionalism and hard work to overcome challenges in completing this app." ⭐ "Excellent work, everything was done as planned." ━━━━━━━━━━━━━━━━━━━━━━━ HOW I WORK ━━━━━━━━━━━━━━━━━━━━━━━ ✔ I take ownership — no micromanagement needed ✔ I flag problems early, not after they cost you time ✔ I communicate clearly and ship on time ✔ If something should be built differently, I'll tell you before I build it wrong ✔ Available for full project overlap with EU/UK working hours (EET) Best fit if you're building a mobile product that needs hardware integration, AI features, or both — and you want someone who treats your product like their own. Let's talk about what you're building.
