Senior Unity Developer — 99 projects, 49 reviews 5/5.
I design immersive and interactive experiences in Unity: virtual reality, augmented reality, serious games, 3D configurators, digital twins, and 3D mobile applications. From training (immersive learning) to event management, including industrial and consumer applications — I cover the entire chain, from technical scoping to deployment.
They trusted me: Sanofi, Saint-Gobain, Octapharma, Pierre Fabre, Metso.
Training (AR / VR / Serious Game)
I design immersive modules for learning gestures, processes, or high-risk situations, with a focus on realism, feedback, and progression.
Typical deliverables: interactive simulation, scoring, guided tutorials, training/evaluation modes, deployment on your headset fleet (multi-brand, Meta Quest) and/or PCVR.
Event Management (trade shows, launches, internal events)
I develop stable and fluid "wow" experiences, designed for intensive use at trade shows: quick startup, intuitive UX, robustness, offline mode, automatic reset, supervision if necessary.
On mobile, I create AR experiences (iOS/Android) adapted for activations: product presentation, augmented tours, AR mini-games.
Industrial & Consumer
3D configurators, explorable digital twins, professional simulators, data visualization, and 3D mobile applications (iOS/Android, WebGL). Interactive tools for selling, training, explaining, or piloting.
Stack (tech)
C#, .NET, VR interactions (XR), ARKit / ARCore, Shaders, CPU/GPU optimization (profiling), REST API, Git.
Work Method
Scoping (educational objective or activation objective, hardware/location constraints), rapid MVP, short iterations with testable deliverables, then stabilization/optimization before production.

Context
Gymnastics application for professional and amateur athletes. After several years of chaotic development and a succession of developers, the codebase had become unstable, unmaintainable, and blocked any evolution.Mission
Complete Reconstruction from ScratchStrategic decision to completely rebuild the application to establish a solid foundation. Migration to Unity 6 with URP to optimize mobile performance, modular and maintainable architecture, reproduction of all existing functionalities while correcting critical bugs.Dynamic Content SystemMajor problem: the application contains hundreds of 3D animations requiring frequent updates. Each modification required a new submission to the stores with a 7-10 day validation delay.Solution implemented:- Dynamic download system via remote server (supports .fbx and .glb)
- Asynchronous loading and optimized memory management
- Real-time updates (animations, exercises, 3D models) without going through the stores
- Deployment time reduced from several days to a few minutes
Additional Features- Multilingual localization (Unity Localization)
- In-app purchases and Premium subscriptions (Unity Purchasing)
- Server synchronization for license validation
- Technical Stack
- Unity 6 (URP) • C# • Addressables • Animation Rigging • REST API • Unity Purchasing • Cinemachine • iOS/Android/Web Publishing
Results✅ Stable application on all devices✅ Content update: 7-10 days → a few minutes✅ Scalable architecture for new features✅ Maintenance costs reduced by 3✅ Client autonomous with no technical skills required - ORBISUnity AR DeveloperENTERTAINMENT AND LEISUREMay 2024 - May 2024 (1 month)Paris, FranceDevelopment of an augmented reality experience for a major makeup brand. The application allowed displaying hand animations on the user's face to demonstrate the application of a new cream. The system relied on real-time 3D face mesh capture using AR tools, allowing precise adaptation of the animation to each user's features and movements.
