I am a Unreal Engine developer with extensive plugin development experience across Unreal Engine 5.x, including 5.0.3, 5.1.1, 5.3, and 5.4.3. Over a 22-year career, I worked in PLM and visualization with Dassault Systèmes and other tech firms, leveraging C++, Python, scripting, and web services to deliver high-performance visualization tools and simulation. Recently, I have been focused on real-time graphics integration, multi-user editing, and asset import/export workflows, building tools that streamline pipelines for AR/VR, medical visualization, and design/engineering workflows. I'm excited to push the boundaries of graphics and interactive technology.
