A bit about me

I'm a full-stack software developer with 7+ years of experience, working mainly with Rust. I enjoy building software close to the metal — package managers, privacy tools and low-level networking — as well as polished user-facing apps.

My open source work ranges from umbra, a zero-trust, post-quantum anonymous communication system running P2P over Tor, to brim and shelly-fedora, modern package managers for Fedora and Debian. I also build Android tooling and design bare-metal security challenges.

When I'm not coding, I'm usually tinkering with my Linux setup, exploring new protocols or contributing to the open source ecosystem.
