Software Engineer -- JavaScript and all things web

Hi, I am Jacky πŸ‘‹

What I do

I work with web stuffs 🌐

I mainly work with JavaScript and all things related to the web ecosystem. Currently, I am working at Tokopedia in the web platform team.

I write (kinda) πŸ—’

I have always been a curious person. I love to learn things and understand how they work. Sometimes if I find the discovery interesting, I try to write an article about them to share them!

I build stuffs πŸ› 

Sometimes I am motivated to build stuffs. Some are just for fun and learning, some are actually kind of helpful. A lot are abandoned because I got sidetracked (don’t we all? πŸ˜…). I published them as open source projects on GitHub. I also contribute to open source libraries when I could.
