I'm macao, a Java backend engineer who writes attendance systems by day and builds small things by night.
This "workbench" is my personal site: handy little tools, a shelf of study notes, and eventually a blog and project shelf. It uses no frameworks — every page is handwritten HTML, CSS and JavaScript, hosted on EdgeOne Pages, and it collects nothing about you.
In the toolbox
Java
Spring Boot
Python
HTML / CSS / JS
