About Maher

Full-Stack .NET Engineer with 8 years of experience, I design and develop robust backend applications and real-time platforms for demanding environments (industry, finance, insurance).
Specifically, I can help you to: design and develop .NET / C# microservices and performant REST APIs; build full-stack web applications (backend .NET + front Vue.js / TypeScript); set up and ensure the reliability of your cloud and DevOps infrastructure (Azure, Docker, Kubernetes, CI/CD); and integrate real-time data streams.
What sets me apart: a dual skill in software development and DevOps, combined with a rare expertise in industrial IoT. In my current mission for a major industrial machinery manufacturer, I am developing a monitoring platform that processes real-time equipment data via MQTT, Sparkplug B, and Azure Event Hub, with SignalR streaming, PostgreSQL/Redis storage, and supervision dashboards.
I am involved in architecture design, development, code review, and testing, as well as deployment and monitoring. I am accustomed to Agile team work (PO, dev, UX, Tech Lead) and I attach great importance to code quality and best practices.
Bilingual French/English, based in Strasbourg and open to remote work.
