Senior Graphics and Signal Processing Programmer | 27 Years of Real-Time GPU Development I specialize in real-time graphics, GPU computing, and 3D visualization systems, large data processing, optimization. Education: Bachelor's in Software Engineering, École de technologie supérieure (ÉTS), Montréal, Québec, Canada. Professional Experience: I've contributed to renowned studios including Gameloft, Ludia, A2M (Behaviour), and Matrox, where I handled quality assurance and AVX2 optimizations. At Smartpixel.com, I led R&D initiatives in Unity 3D rendering using C# and custom shaders, alongside WebGL projects with various engines and APIs. I collaborated with Chisei Technologies, a Ukrainian startup developing hyper-realistic VR character rendering technology. Unfortunately, the company had to cease operations due to the war. For the past years, I've been working with Groupe Trifide, a land surveying company, on Trifide 360—a high-performance application for visualizing and measuring point clouds up to 100 GB, combining LIDAR scans and photogrammetry from drone imagery. I engineered an efficient streaming system enabling real-time display of massive datasets with instant per-point selection via mouse interaction. Side Projects: Vision EEG / Brain2Midi: Android application converting brainwave frequencies into music and visual effects; High-performance computing library: C++ OpenGL/OpenCL signal processing framework
