About me
I found HTML and CSS when I was 12. I started with small JavaScript games, and today I build websites and web apps with React and Next.js, making sure they load fast and anyone can use them. I also build educational apps and sites for presentations or specific purposes, like interactive simulations.
I study Software Engineering at ESPOCH in Riobamba, Ecuador. I'm Chair of the IEEE ESPOCH Student Branch, where I was previously webmaster. I'm part of the CONESLAT 2026 organizing team, and I was master of ceremonies at the gala dinner of the IEEE Ecuador RNR 2026.

Away from the code
I watch anime with a frontend eye: I notice the timing of the animation, the framing and how each shot guides your attention.
- One Piece
- Naruto
- Black Clover
- Hunter x Hunter
And chess
I also play chess. I enjoy calculating several moves ahead and finding the plan behind each position, the same way of thinking I use before writing code.
