About Nicolas

Expert C++/Qt & Flutter 🚀 | System Performance & Modern Apps

Need to combine the power of C++ with the fluidity of Flutter?
Independent and lecturing at the University of Limoges, I help companies transform complex systems into intuitive and performant products.

Count on a rare dual expertise to secure your technical launch strategy:

✅ Performance & Data (C++/Qt): Optimization of critical algorithms, management of 3D/point cloud streams, and robust architectures (Expertise inherited from GolemLabs & Kreon).

✅ User Experience (Flutter): Design of MVPs and mobile/desktop applications with a smooth user journey, polished animations, and guaranteed scalability.

✅ Consulting & Pedagogy: Teaching from Bachelor's to Master's level, I help you make the right architectural choices to avoid technical debt from the start.

🛠️ Mastered Stack:

System/Desktop: C++ (17/20), Qt / QML, CMake, Unreal Engine.

Mobile: Flutter & Dart, Native Android, Firebase.

Data/Backend: Python, REST API, Hardware Integration.

Why choose me?
I bridge the gap between hardware/low-level and modern interfaces. You get academically clean, documented code and total responsiveness (Remote or Limoges).
