Network engineer.
I build the tools I use.

I'm Adam El Hejaji. I design and build networks: routing and switching, firewalls and VPNs. In my spare time I build open-source macOS, iOS and web software. My Raspberry Pi VPN travel router won Silver at ESTE'25.

Raspberry Pi VPN Travel Router

Final year project · SEGi University · 2024–2025

A portable, low-cost router that puts your devices behind a VPN on public and hotel Wi-Fi. I set up the VPN tunnelling, routing, firewall rules and DNS handling on Linux, then tested throughput and connection stability.

My fork of the open-source break-reminder app. I redesigned the UI to feel native on macOS, drew a new app icon, logo and tray icons, and added pausing breaks while the camera is in use (#969). I also fixed a crash when quitting during a break and a colour-swatch bug.

How I work

I start by asking what the problem is, explain changes in plain language, document as I go, and follow up until the issue is closed. I'm comfortable doing live demos and presenting to judges, management and customers.
