ABOUT
Hi, I'm Junzhou 【猫猫】
I like problems that end in products.
I'm a 22-year-old developer interested in building useful digital products. My work spans websites, web applications, custom software, business systems, desktop and mobile applications, integrations and automation.
What I enjoy most is the practical part: understanding what someone actually needs, and then building a solution around it.

ABOUT
How I approach work
- 01
Understand first
I start by understanding what someone actually needs — the problem, the people and the goal — before choosing technology.
- 02
Build to work
I care about products that function properly in the real world: fast, reliable, maintainable and tested.
- 03
Stay practical
I'm one developer, not an agency. You talk directly to the person who designs and builds your product.
