Project details
You will get an MAUI application that will run in .NET 7 and work with Android and IOS build. I have worked on Xamarin Forms for 8 years and I know how important it is to migrate now, I have seen most of libraries issues while porting to MAUI.

.NET MAUI iOS & Android Native Library Wrapper Proof of Concept App
Hassan worked on a very large and complicated .NET Maui SDK integration. He wrapped native iOS and Android SDKs with .NET wrappers and did advanced debugging and runtime optimizations. He has expert knowledge on the internals of the tech stacks up and down. But the most impressive skill is his communication and his ability to work around timelines and within our time zone. I never had a doubt we hired the right programmer for this job.
If you have a project that needs a real expert in .NET, .NET MAUI, iOS, Android, or even web / cloud technology (he worked on some Azure Functions as well) -- I would HIGHLY recommend Hassan. You will not regret hiring him!

Job Success
Rome, Italy - 8:10 am local time
What makes me useful to founders and product teams: I cover the full stack with AI layer (LLM integration, RAG pipelines, on-device ML, computer vision) through to the mobile or web product it lives inside. That means I can meet you wherever you are, whether you need help thinking through the AI architecture, building the app around it, or both. Fewer handoffs, faster iteration, and someone who stays accountable for the whole thing working in production.
🔹 Selected Projects
✔ Fitabase — Garmin Health SDK integration in .NET MAUI
Built the first .NET MAUI binding for the Garmin Health SDK from scratch. No prior bindings existed — I wrote the native iOS and Android bridges, exposed them through a clean MAUI API, and shipped it into Fitabase Engage, a platform used by health researchers to collect data from thousands of wearable devices. This is visible on my Upwork review history.
✔ PoolExpert (Zepto Internet Solutions, Canada) — Xamarin.Forms → .NET MAUI migration
Migrated a production mobile app with 100,000+ users from Xamarin.Forms to .NET MAUI without service interruption. Audited every page, identified the right MAUI controls based on performance profiling, and rebuilt the architecture for faster load times and smoother UI. Ongoing engagement — the client kept me on after migration for active feature development.
✔ Xplor Platform (UK heritage organization, via DataDuopoly)
Senior Engineer and Technical Lead on a commissioned platform for a major UK heritage organization. Owned the migration of a legacy system and led the design of a footfall prediction algorithm to help operations plan visitor capacity across sites. Delivered and deployed to production.
✔ Pryzebox (Vivomi Inc.) — 2-year multi-platform engagement
Built and maintained an entire e-commerce stack: a Shopify-embedded app, mobile apps (Xamarin iOS/Android), a .NET Core + Entity Framework web admin panel, and the supporting REST APIs. One engineer, four surfaces, shipped and maintained over two years.
✔AILEVEN — Italian fantasy football platform
Full stack build: mobile app, backend, and admin panel — all in C# and .NET. Currently planning the .NET MAUI migration with the founder.
✔ 12-Lead ECG Arrhythmia Detection (MSc research, Sapienza)
Built a Flutter app running custom-trained deep learning models (TensorFlow Lite) for on-device ECG arrhythmia classification. Trained and compared multiple model architectures for my thesis. Published research on arXiv. Demonstrates genuine applied ML depth, not just API integration.
✔ RAG-Powered Book Summary Platform (Claude API + Google Workspace)
Designed and built a Retrieval-Augmented Generation pipeline that produces long-form book summaries users can publish and share. Built for a fraction of the cost of off-the-shelf alternatives by architecting smart chunking, caching, and context management. Launching to production soon.
🔹 How I can help you
If you're an AI-first founder building an MVP — I'll architect and ship it end-to-end: the AI layer (RAG, agents, LLM features), the product it lives in (mobile or web), and the infrastructure under it. You get one senior owner, not a team of handoffs.
If you're an enterprise mobile team — I lead complex .NET MAUI and Flutter builds, with specific depth in migrations from Xamarin, integrating SDKs that don't have bindings yet, and layering AI features into existing apps.
If you're an agency — I take on senior technical engagements as a subcontractor where AI and mobile skills both need to be real. References available.
🔹 Tech Stack
AI & ML: Python, TensorFlow, PyTorch, scikit-learn, LangChain, Claude API, OpenAI API, Gemini, RAG architectures, vector databases, TensorFlow Lite, NCNN, on-device inference
Mobile: .NET MAUI, Flutter, Xamarin.Forms, Xamarin Native (iOS/Android)
Backend: .NET Core, C#, Entity Framework, Python/FastAPI, Node.js, REST APIs, microservices
Cloud & DevOps: AWS, Azure, GCP, Docker, Kubernetes, GitHub Actions, Azure DevOps, CI/CD
🔹 How I work
Clear weekly updates. Honest estimates, including when things will take longer than I hoped. Code that another engineer can take over without a month of onboarding. I'm in CET and overlap comfortably with US East Coast and UK hours.
I don't take $500 projects, "build me ChatGPT in a week" briefs, or work I can't do well. If your project isn't a fit, I'll tell you and point you to someone better.
Send me a message with a few lines about what you're building and the problem you're trying to solve. I reply within 24 hours with an honest read on whether I'm the right person — and if I'm not, I'll say so.
