What I Build

Small tools with a sharp edge.

The site is both a portfolio and a living product lab: public tools, technical writing, and experiments that make everyday digital work more direct.

Workflow lens

I prefer tools that remove a real step from someone's day: no-upload video utilities, private translation flows, local AI commit helpers, and browser surfaces that stay close to the page people are already using.
