Oscar Fernandez

Hi! I'm Oscar Fernandez, 18 y/o backend dev and hobbyist security researcher from Mataró, Barcelona. I spend most of my time in the Python ecosystem, whether that's building backends or digging into systems I probably shouldn't. I also build and contribute to open source whenever I get the chance.

This is where I write about it.
