Principles

What guides
my work.

1

Understand the layer below.

Read the code, investigate the system and understand the machine. Abstractions get better when we know what happens beneath them.

2

Simplicity is a decision.

Choose tools to fit the problem. Make the system readable, predictable and maintainable for the people who come next.

3

Knowledge grows when shared.

Contribute code, documentation and community work. Sharing the process is part of building, too.

4

Security from the start.

Consider trust boundaries, data and operations alongside the architecture. Security is part of everyday engineering.

Stack

Rust + Unix

I lead CybercodeBR, a community hub for open-source developers in Brazil, with free events, content for every level and open projects.

Community · Leadership & organization

Omarchy Brasil

I created and organize this monthly online series on Omarchy, Hyprland and Linux workflows for developers. Streamed on YouTube and listed on Omarchy's global meetup calendar.

Curation & hosting

Talks with guests from the community, from migrating to Linux to running self-hosted AI agents such as Hermes Agent on the system.

Community structure

I defined participation levels, member-supported events, a code of conduct, a developer residency and public financial transparency.

Repositories & infrastructure

I maintain the organization's repositories — website, talks and configs — and the event infrastructure across Luma, YouTube and Discord.

I’m also a musician. Music, composition and languages are other ways I create and express myself.
