About

I build things, then end up improving them just because I can’t leave them alone

I’ve been writing code for around 4 years. I’m still the kind of person who sees an animation and thinks “how did they build this?” , and then ends up digging into it. I like colors, motion, and small interactions, and I enjoy turning those into real features.

I mainly work on the frontend side with React and React Native, but I don’t really like staying in a single box. I tend to jump into backend logic, API design, or UI systems whenever something interesting shows up.

I’m not strictly following a “T-shaped engineer” idea — I’m more into going wherever the problem or curiosity leads.
