About

I'm Mateus. I build software and content with AI agents: desktop apps for macOS, web tools, and the kits that make the next build faster. Everything here is open.

What I build

Four open projects, one line each for what they do.

web.ai

Turns a design into a WordPress page the client can edit alone, with the layout kept intact.

monitorpilot

Controls every screen on the Mac from one menu: brightness, resolution, an extra screen and one picture inside another.

cove

Puts the black bar at the top of the Mac to work: what is playing, what you dragged and what you copied before.

Character Kit

Create a character once and keep the same face in every image you generate after that.

vibe100coding kit

The way I work, written down: how to go from the idea to the product live.

How I work

Every change goes through automated checks before it counts, and a red check is never worked around, commented out or ignored.

Where I publish

Technical notes ship in Portuguese and English, always as a pair. The first contact is usually on Instagram, and the conversation continues in the Vibe100Coding Club.

Tools, agents and content. Shipped in public.
