Builder since
day one

I'm 12, in 6th grade at G.W. Carver Middle School in Miami. I co-built mvrtnBot with my dad, deployed my first site, and I've been shipping ever since. Future architect - but right now I'm building software.

🏗️

Architecture

Future career goal. Until then, building digital things with the same precision.

🕹️

Gaming

Roblox, Geometry Dash. Gaming is where I first saw what software could do.

🌍

Travel

HKG, Genova, Como, Milan this summer. CityWise came from wanting this info in one place.

📚

Mystery reads

Currently: Strange Houses by Uketsu. Psychological thriller, not gore. Good tension.
