// what four years of shipping taught me
— SO THAT'S WHAT I BUILD TOWARD.
01 — THE PERSON BEHIND THE WORK
As a Flutter developer, mobile application engineer, and IoT application specialist, I've shipped for clients across Germany, the Netherlands, the United States, the UAE, and Iraq — from a music-medicine app for a German university to centralized IoT hubs controlling entire device ecosystems.
Mobile, AI, IoT, automation, backend — on paper that's a wide range. In practice it's one discipline: match the technology to the problem, not the other way around. It's why a hardware company trusted me with a custom BLE protocol the same year I shipped an AI automation pipeline.
I also build my own products. CertifyCrafter — a live SaaS platform — taught me to think like an owner, not just an engineer. Being a founder myself means I understand the stakes when you hand someone your idea.
Most of my work is under NDA, and I treat that as a professional standard. When you hand someone your idea, you're trusting them with something fragile — that discipline is exactly what you'd want protecting your own project.
02 — IDEAL CLIENTS
You have an idea. You need someone to build it — a reliable technical partner for your MVP, without hiring a full team.
Your product works. Now it needs to scale. Features, architecture, and the systems that support growth.
You need execution, not management overhead. A senior developer who plugs in and delivers.
You know AI can help. You need someone to build it — workflows, automation, and intelligent product features.
03 — WHAT I BUILD
iOS & Android apps engineered for performance and growth — apps people actually keep on their phone.
/02Intelligent systems that buy back your time — AI agents, LLM integration, and workflow automation.
/03Where physical devices meet digital systems — BLE protocols, real-time sync, embedded comms.
/04From concept to launch-ready product, fast — scoped honestly and shipped while the window is open.
/05Scalable backends that grow with your product — auth, data, and the APIs your roadmap depends on.
/06The right decisions before you build — architecture, technology choices, and code review.

05 — CLIENT REVIEWS
✓ ALL REVIEWS INDEPENDENTLY VERIFIED ON UPWORK ↗
★★★★★“He understood the business before writing a single line of code.”
We came in with a rough idea and Mohamed turned it into a real, shipping mobile app. Delivered ahead of schedule. Genuinely felt like a partner, not a contractor.
★★★★★“The most reliable developer I've worked with on Upwork — full stop.”
Our BLE integration was complex and several developers turned it down. Mohamed architected an offline-first system that cut our sync errors dramatically. Communication was flawless.
★★★★★“He automated a process that was eating our whole week.”
Mohamed designed an AI automation system that handles it end to end. Saved us 15+ hours every week and it just works. Already hired him for a second project.
06 — TECHNICAL EXPERTISE
Technologies are tools. I choose based on what fits the problem — not what's trendy.
