My name is Antonis Geralis. I am a computer science graduate. I speak 🇬🇷 Greek (native), 🇺🇲 English and 🇩🇪 German. I code mostly in Nim, but I am quick to pick up new languages and frameworks. My programming interests include multithreading, machine learning, fuzzing and vulnerability assessment, making indie games and web-apps. I love solving hard problems and learning about Computer Science.
