Hi, I'm Fábio Mendes 👋

I'm a systems administrator and cybersecurity practitioner with 10+ years managing critical infrastructure, currently building open-source tools focused on security, privacy, and defensive engineering.

🐣 Highlight Project: Chirp (usechirp.app)

Remote assistance tools are essential, but the current market is broken: commercial tools are bloated with aggressive subscriptions, and existing solutions are routinely weaponized by phone scammers targeting regular people.

Chirp is remote help between two people who trust each other:

  • Zero install & zero accounts: Download single binary, run it, share your code or link, and close it when done. Nothing stays behind.
  • Scam-resistant by design: The consent prompt puts Decline in focus, delays Allow by 3 seconds, displays names as unverified claims, and grants view-only access unless explicit control permissions are toggled.
  • Permanently free & self-hostable: No feature gates on mouse/keyboard or file transfer, and full freedom to run your own signaling and relay servers.

💡 Why Sponsor?

Developing network-intensive, multi-platform desktop software and security tooling requires real infrastructure:

  • Relay & STUN/TURN servers: Keeping low-latency, resilient public relay nodes running for users behind strict NATs.
  • Cross-platform testing labs: Maintaining build pipelines and physical/virtual testbeds across Linux, Windows, and macOS.
  • Dedicated development time: Accelerating development milestones towards stable releases, protocol audits, and community packaging.

Every dollar helps maintain these servers and guarantees that Chirp remains independent, open-source (AGPLv3), and secure for everyone.

Thank you for supporting independent, scam-resistant open source! ☕
