✅ 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.
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.

𝗪𝗵𝗮𝘁 𝘆𝗼𝘂 𝗴𝗲𝘁:
✔️ A clearer UX structure from the start so the product is built on solid logic, which means you do not end up polishing screens that break under real usage.
✔️ Design that works with real content so the interface survives actual product conditions, which means it does not collapse when fake placeholder text gets replaced with real names, data, and system states.
✔️ Critical flows tested before handoff so hidden friction is spotted early, which means fewer conversion leaks in onboarding, activation, and feature usage.
✔️ UI that guides action so users move through the product with less effort, which means better clarity, faster decisions, and less drop-off in important moments.
✔️ Handoff with system thinking behind it so implementation is more predictable, which means less dev guesswork, less patching, and fewer “we’ll fix it later” compromises.

✔️ A stronger flow of attention across the page so people know what matters and where to look next, which means less friction, less hesitation, and better conversion.
✔️ A cleaner handoff for development so the final build is more predictable, which means less patching, less rework, and fewer surprises after design.

✔️ Core states designed upfront so the experience holds up beyond polished mockups, which means fewer broken moments when real usage hits the product.
✔️ Interfaces that make actions easier so users can complete key tasks faster, which means smoother sessions, less frustration, and better flow inside the app.

✔️ A redesign shaped around what is not working today so weak sections and outdated patterns get fixed with purpose, which means the site performs better instead of just looking newer.
✔️ A stronger visual system across the site so the brand feels more credible and up to date, which means you build more trust before the pitch even starts.
✔️ Pages designed to scale more cleanly so future updates are easier to add, which means the site can grow without becoming harder to manage.
✔️ A cleaner handoff into development so implementation is smoother and more predictable, which means less rework, less patching, and fewer surprises after redesign.

I focus on helping startups and businesses to leverage AI and adapt to modern software industry which is now more accessible than ever. That includes full-stack development, AI automation, prototyping, custom development and of course taking over what you already built and turning it into production grade solution.
🔐 𝗞𝗲𝘆 𝗦𝗲𝗿𝘃𝗶𝗰𝗲𝘀:
1. Full-stack development — end-to-end product building, front to back
2. AI automation — streamlining workflows and processes with AI
3. Prototyping — fast, working proof-of-concepts to validate ideas
4. Hardening — taking over what you've already built and turning it into a production-grade solution
🌠 My background is in custom software development, and I spent a while working as a hands-on engineer. I was lucky enough to spend my entire career working with fast-growing, large-scale, and enterprise clients, representing an outsourcing vendor.
🌌 Apart from development activities, I was engaged in many others: interviewing engineers, participating in pre-sales, training programs, leading and driving development processes, and much more. I was always a company guy and was interested in and open to everything.
👴🏻 That’s where I matured as an engineer. I learned a lot along the way, saw how painful the software development process could be, and understood the pros and cons of different organizations, including where Fortune 100 companies struggle.
📺 I’m a professional engineer focused on delivering business outcomes for you — not a part-time freelancer juggling Upwork with a full-time job or doing it for extra income. I'm working with all types of clients and budgets.
✅ 99% Job Success Score; 100 + projects delivered — from idea to production-ready software
🛡 Expert-Vetted — interviewed and approved by the Upwork team
🚀 Fastest-Growing Upwork Profile Globally — $4M+ earned across multiple profiles since 2022
🌍 Most Recognized & Viewed Upwork Profile Worldwide
💰 Scaled 5 Upwork Profiles to $300K+ revenue each with strong inbound leads
🏢 Delivered Projects for Fortune 100 & Inc. 5000 Companies and UAE government
🧠 Led Pre-Sales, Estimations, Code Reviews & Tech Interviews for top-tier clients
💻 Even if we don’t end up working together, I’ll help you identify risks and guide you on how to make the product happen — because in the end, it’s all about mindset, not just coding skills.
💡 Answering a question how am I different in this competitive AI industry — the answer is simple: mindset. You can learn endless frameworks, libraries, languages — alright, cool, but mindset and deep understanding of this world outside and inside the industry is what really makes a difference.

As a Software Developer and Senior Web Developer, I bring a backend-first mindset to every engagement, with deep attention to scalability, SaaS Development architecture, and long-term maintainability.
Core Specializations
Full Stack Mobile App Development
As a Full Stack Mobile App Developer and React Native Developer, I deliver cross-platform iOS and Android applications that perform like native products. As a Flutter Developer and Flutter Mobile App Development specialist, I build unified experiences where a shared codebase does not mean compromising quality. As a Mobile App Developer covering mobile app design, mobile app development, and full deployment lifecycle, I treat performance and reliability as non-negotiable from day one - not afterthoughts.
Full Stack Web & React Development
As a React Developer and Full Stack Developer, I build end-to-end web solutions using React, Vue, Next.js, and TypeScript on the frontend. As a Web Developer handling both Web Design and component architecture, I create scalable, maintainable interfaces backed by Python (FastAPI, Django, Flask), Node.js, and Laravel. As a Full Stack Developer with React and Node.js expertise, I own delivery from database schema to deployed product - clean API contracts, proper state management, and optimized data flow across every layer.
SaaS Development & Backend Architecture
As a SaaS Developer, I design and build SaaS Development platforms from MVP to mature multi-tenant products - including subscription logic, role-based access, and SaaS business development-ready architecture. As a Python Full Stack Developer and Backend Developer, I build robust APIs with Node.js and Python for high concurrency workloads. As a Full Stack Developer PHP specialist, I also support Laravel and PHP-based ecosystems when projects require it. As a DevOps-minded engineer and React Native Developer building mobile-connected SaaS platforms, I manage infrastructure as code across AWS and Microsoft Azure environments.
AI Integration & Cloud Infrastructure
As a Full Stack Developer focused on AI Integration, I connect web and mobile frontends to AI-powered backends - implementing smart search, real-time suggestions, and LLM-driven features using OpenAI API and LangChain. As an AWS Architect with expertise in AWS (Lambda, S3, DynamoDB), Microsoft Azure, and Azure DevOps, I ensure data handling is high-speed, cost-effective, and secure across Web, iOS, and Android platforms. As a React Web Development and API Integration specialist, I build the connective layer that makes AI functionality feel responsive and production-ready.
