About me


I'm a full-stack software engineer who learned how to code when I was 14. I wanted to make my own video games, and I immediately fell in love with it. Not just the ability to create anything I could imagine, but the process of solving the technical challenges along the way.

I'm also a speedcuber, I love the pattern recognition skills and dexterity required. I learned how to solve a Rubik's cube when I was 12, and from there I branched out to other puzzles. I have a collection of around 70 different ones. I can solve a 3x3 in ~12s, and my best time is 5.35s.

I'm a semi-professional pool player as well. My dad taught me how to play when I was 10, but I didn't start taking it more seriously until my early twenties. I play a few tournaments a month and I tend to do well. I love the social and competitive aspects of it.
