GuardLite

A no-root personal firewall for Android, fully on-device.

GuardLite is a lightweight personal firewall for Android. It gates the device's network traffic locally through the system VPN service — no root access required, and nothing leaves the phone. Built as a modular Kotlin app, it gives people a clear view of what their apps are talking to. Completely free, distributed as a signed APK.

Open to collaborations and technical opportunities.

I take on a small number of engineering and AI projects each year — mostly practical, often maritime-adjacent. Happy to talk if the problem is concrete.
