TRUENINE / ENGINEER & ACCESSIBILITY ADVOCATE

Build thoughtfully.
Share openly.

I'm TrueNine, a full-stack developer from China building reusable developer tooling, AI-assisted engineering workflows, and software that works for more people.

Accessibility is part of the architecture.

01 / SELECTED WORK

Featured projects

Small, focused tools for teams that care about the details.

02 / NOTES TO SELF

What I care about

01

Accessibility by default

Software should remain understandable and operable with assistive technology.

02

Maintainable systems

Strong boundaries, explicit contracts, and code that survives beyond the first release.

03

Test-driven development

Feedback should arrive early, before mistakes become architecture.

04

Practical AI workflows

AI should improve engineering judgment, not replace it.

05

Sustainable open source

Shared tools get better when knowledge and improvements flow back to the community.
