Pol Roca Cerdá

Graphics Programmer & C++ Engineer

Computer Science and Master in Research and Innovation graduate from UPC. With professional experience as a Software Engineer and Researcher at Vall d'Hebron, ViRVIG, and EY, I specialize in solving complex visual computing problems. My work focuses on building efficient real-time rendering pipelines, GPU compute shaders, and interactive medical visualizations, backed by a strong foundation in Applied Mathematics.
