Johnny-Kao/README.md

Last updated: 2026 May 22

Hi there ๐Ÿ‘‹

I'm Johnny Kao.

A lot of my professional work lives on johnnykao.com.
This GitHub is a bit different. It is the more experimental, more personal side of me, with selected code, passing curiosities, and ideas I feel like keeping around.

I spend most of my time around finance, strategy, cross-border questions, and digital systems, but I have never liked staying in just one lane.

๐ŸŒ Other Languages: ไธญๆ–‡ | ๆ—ฅๆœฌ่ชž

๐Ÿ’ก About Me

I tend to live in two worlds at once.

One is the professional world: cross-border finance, strategic work, trust-sensitive environments, and decisions that carry real weight.

The other is more personal and open-ended: strange internet rabbit holes, small experiments, tools I build for myself, and ideas that start as a passing thought and refuse to leave.

This GitHub sits somewhere in between.
