Become a sponsor to Leo Cavalcante

Hi, I’m Leo, a software engineer from Brazil.

I build tools that I want to use in my own work, and share them so other developers can use them too. You might know me from Siler, my PHP toolkit, or encrypt, my Dart cryptography library.

These days, I’m working on developer tooling and AI-assisted workflows. My recent projects include:

• pi-subagents: isolated subagents with parallel execution, chained workflows, and background jobs.
• pi-tmux: task-aware tmux window names and indicators for agents waiting for input.

I also share notes on software engineering, infrastructure, and AI at leocavalcante.dev.

Sponsorship would help me dedicate more time to these projects: fixing bugs, improving documentation, and developing new tools.

If something I’ve built has helped you, sponsoring me is a way to support what comes next. Thank you!
