$ whoami

Terminal card: Arnau Blesa, research engineer at IEEC and MSc RICSE student at UAB, working on GPU, HPC and AI

MSc student in Research and Innovation in Computer-Based Science and Engineering (RICSE) at Universitat Autònoma de Barcelona, and part-time research engineer at IEEC. I like making heavy computations fast: GPU programming, AI acceleration, numerical simulation and large data pipelines.

Looking for R&D roles in GPU computing, HPC and applied AI.

$ ls ~/projects

├─ r2net-cuda/

CUDA acceleration of the R2-Net neural lossless image coder, comparing wavefront and fully parallel GPU strategies.

Python · CUDA · CuPy · NumPy 		├─ neural-fluid-simulator/

A U-Net trained on lattice Boltzmann simulations that predicts vortex shedding 52× faster, on obstacles and Reynolds numbers it never saw.

Python · PyTorch · NumPy
├─ kerr-black-hole-simulator/

Real-time Kerr ray tracer in GLSL that follows light through curved spacetime to render gravitational lensing and the accretion disk. Validated against analytical results.

C++17 · GLSL · raylib · CMake 		╰─ survey-tabulator/

Desktop tool that turns SPSS .sav surveys into weighted frequency tables (Excel and PDF). Tabulates two-million-row files in 15 seconds without loading them into memory.
