About me

I am Rached Waly, a C++ Software Engineer at Dassault Systèmes focusing on high-performance 3D data processing and spatial algorithms. I specialize in architecting efficient computational pipelines using advanced data structures

My current work involves designing scalable systems for large-scale 3D scene processing, implementing parallel algorithms that achieve 3x+ performance gains, and creating reusable software architectures. I excel at optimizing computationally intensive algorithms for both high-end workstations and resource-constrained embedded platforms.

Previously, I architected real-time 3D systems for HoloLens 2, where strict hardware constraints demanded innovative approaches to spatial indexing, memory management, and algorithmic efficiency. This experience taught me to deliver high-performance solutions within severe limitations—skills I now apply to large-scale data processing challenges.

My education at Télécom Paris and Institut Polytechnique de Paris provided a strong foundation in computer science fundamentals, which I apply daily: designing polymorphic data structure frameworks, implementing multithreaded processing pipelines, and optimizing critical code paths through profiling and algorithmic improvements.
