About me

What I enjoy most is rolling out features that we worked hard before, then seeing users using it. Sometimes is squashing some bugs, who knows. I'm more an introvert but I do enjoy face-2-face interact. Yes, I love people.

I also love spending time experiment pet projects and follow trending stuff on GitHub such as Rust, Next.JS, Svelte (very competitive to ReactJS), Flutter, React Native.

I believe these things keeps me updated and by learning new stuff, I have such a good time to review what I understand, what I don't and somehow it became my routine.
