Hi, I’m Vincent.

Hospitality, then library and information science. Now building tools with Claude, documenting the journey.

Building with care for the people who use it — and the community around them.

THE MISSION
01

People and community first before profit.

A product should be good for the people using it before it makes any money. I try to keep that order.

02

I am working on honest marketing and an honest build.

Honest marketing — if I claim something works, you can go and check it. Every number here says where it came from and when I checked it.

Honest build — it does what this page says it does. When it doesn’t, I say so, with the date.

Let me know if I made a mistake — I will fix it.

03

I want to help set the standard, so that the technology industry doesn’t go into a vicious cycle.

Technology should answer to the people it affects.

Let’s build a better future, together.

Reading the star chart

TAIWAN

Hospitality, then library science. I build with Claude. I’m not an engineer.

I direct the work, test it, question it, and take responsibility for what ships. Some of it I understand deeply, some not yet — this site exists so you can watch me close that gap.
