About Yvan

Specializing in the .NET / C# ecosystem and the Unity engine, I assist companies with complex technical challenges where latency and data sovereignty are critical.

My approach is based on deep code optimization and the use of local AI (ONNX) to deliver intelligent solutions without cloud dependency.

Accustomed to collaborative environments and Agile methodologies, I can quickly integrate into a project team to bring my technical expertise.

My areas of intervention:

Architecture & Performance: Design of robust systems, memory management (Object Pooling), latency optimization (AI inference < 40ms).

Artificial Intelligence: Integration of Deep Learning models via ONNX, Reinforcement Learning (Q-Learning) and algorithm optimization.

Simulation & Real-Time: Development of complex tools and systems under Unity 3D for industry or R&D.

Why work with me?
Beyond writing code, I bring an architect's vision to ensure the scalability and efficiency of your projects. My goal is to transform your technological needs into performant, fluid, and maintainable products.
