About Me

• Name: ArcCosine
• Favorite tools: Vivaldi, Vim, Happy Hacking Keyboard

I am expert in JavaScript. I'm especially good at front-end stuff. I'm not currently accepting work, sorry.

As for recent developments, here's a blog post about it.(mostly in Japanese.)

I have many feelings about various tools, but I especially like HHKB so much that I have purchased several of them. I am such a person, but recently I have become interested in self-made keyboards.

Editor

I love the Vim! No matter which programming language you work with, everything is handled in Vim. But recently, I have begun to make use of NeoVim. My possibilities are still endless:)

Terminal

I can handle any terminal environment myself, but the one I have been working with the longest is probably the command prompt:). Just recently, I have become interested in wezterm.
