I'm passionate about learning, I like to create tools that improve the lives of other devs, and sometimes I recreate things that already exist just to understand their internal mechanisms. In my free time, I like to read about various subjects from philosophy to stories about dystopian futures. I also like to write about tech and philosophy, as well as recreating famous projects (e.g., JVM compiler), just to learn how things work under the hood.
