Give me an app idea, an unfinished product, or a broken mobile feature, and Iโll build or fix it so it works reliably for your users. Thatโs my promise.
Send me an invitation or message with your requirements, and Iโll explain how I can help, what needs to be done, and the best way to move forward.
A little more about me
I help startups, businesses, and development teams build, test, improve, and launch production-ready mobile applications for iOS and Android.
Whether you need a complete app developed from Figma, an existing codebase fixed, a third-party SDK integrated, an app thoroughly tested, or an App Store rejection resolved, I can handle the complete process from development to release.
I treat every application like my own product. That means I think beyond writing code and focus on user experience, maintainability, performance, reliability, scalability, and what could go wrong after launch.

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 โ 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 โ a live B2B SaaS product โ solo. So I know what it takes to own a product, not just contribute to one.
โโโโโโโโโโโโโโโโโโโโโโโ
WHAT I BUILD
โโโโโโโโโโโโโโโโโโโโโโโ
โ Flutter apps with deep native hardware integration (BLE, MQTT, platform channels)
โ AI agents and LLM-powered features inside real mobile products
โ End-to-end IoT systems: device communication โ mobile app โ cloud backend
โ Cross-platform mobile apps (iOS & Android) with Firebase/Supabase
โ Internal business tools, dashboards, and workflow automation
โ Full SaaS MVPs from concept to production deployment
โ OpenAI & LLM integrations (RAG, function-calling, agents)
โ API design and third-party integrations

โญ "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." โ German Medical University (Flutter + Supabase project)
โญ "Mohamed was an excellent freelancer, showcasing professionalism and hard work to overcome challenges in completing this app."
โญ "Excellent work, everything was done as planned."

HOW I WORK
โโโโโโโโโโโโโโโโโโโโโโโ
โ I take ownership โ no micromanagement needed
โ I flag problems early, not after they cost you time
โ I communicate clearly and ship on time
โ If something should be built differently, I'll tell you before I build it wrong
โ 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 โ and you want someone who treats your product like their own.

I build reliable, production-ready Flutter applications that are designed to perform well long after they're launched. My QA background helps me catch issues before your users do, resulting in smoother releases, fewer bugs, and lower maintenance costs.
Using Flutter, Firebase, REST APIs, BLoC/Cubit, and clean architecture, I develop scalable mobile applications that are fast, maintainable, and built for real-world use.
Unlike many developers who focus only on implementation, I also validate user flows, investigate edge cases, reproduce bugs, and thoroughly test every feature before release. This development-first, QA-focused approach helps deliver polished apps that users can rely on.
I've worked on mobile applications across multiple industries, including:
โข Logistics & Transportation
โข Renewable Energy
โข Service Marketplaces
โข Business & Productivity Solutions
Core Flutter Development
โ Flutter App Development
โ Firebase Integration
โ REST API Integration
โ BLoC / Cubit State Management

โ Performance Optimization
โ Bug Fixing & Feature Development
โ App Store & Google Play Deployment

โ Mobile App Testing
โ Functional & Regression Testing
โ UX & User Flow Validation
โ Edge Case Testing
โ Detailed Bug Reports with Screenshots & Screen Recordings
Whether you need a Flutter developer to build a new application, improve an existing product, fix complex issues, or thoroughly test your app before release, I can help you deliver a stable, high-quality mobile experience with confidence.
