Hi! I'm Jaime Walter Pérez. I'm from Jerez de la Frontera, Spain, and I'm currently a senior studying Computer Science at the University of Pennsylvania (BSE in Systems + Submatriculation MSE in AI). Recently I have also completed an SDE internship at Amazon in Madrid.

I'm especially interested in backend and cloud engineering and AI systems—both reliable AI-powered applications and the infrastructure behind model inference. And, as you'll see here, I also enjoy making projects that are playful and fun to interact with.
