freelance software & systems · cybersecurity

Freelance software and systems, based in Timișoara, Romania. I work between operations and development: building tooling for Linux, and spending a good part of my time on cybersecurity. My default is evidence — tools that show what is actually happening on a machine, backed by tests, rather than asking for trust.

Linux Doctor — read-only diagnostics for Linux. ~49 checks, a 0-100 health score, and a run-over-run diff (new / fixed / unchanged) with a fix for every finding. One engine behind a CLI, a web dashboard and a desktop app (Tauri). GPL-3.0, 600+ tests, no runtime dependencies. Packaged for npm, OBS (Fedora/RHEL/openSUSE), AUR, deb, rpm and AppImage.

• Linux system tooling and diagnostics
• Automation, CI and packaging
• Cybersecurity

• Read-only by default; side effects must be explicit.
• Test what you ship.
• Clear output over clever output.
• Direct and async.

Open to freelance work and collaborations: Linux tooling, automation and security.
