Leonardo Lucas de Castro Filho

I'm Leonardo, a developer from Brazil. My work splits between three things I enjoy: building tools that let AI coding agents work the way a careful developer would, reverse engineering online services to build native Linux clients for them, and automating the repetitive side of running a business, from CRM pipelines to marketing. I write most of my tools in Rust, on a Linux desktop I set up from scratch and never stop tweaking. jujutsu-mcp started because my agents kept fighting the version control I actually use. Everything I publish here is something I run in my own work, and the code behind it is open on GitHub.
