I break things to understand them.

IT Operation Engineer @ EQOM · Network & Security Engineering @ Hanze
I build self-hosted tools, investigate systems, and photograph light when I'm away from a terminal.

Curiosity is the through-line: networks, data, and light all give up their secrets if you look long enough.

I'm happiest where security meets curiosity.

Roan Heemstra. Network & security engineering student at Hanze, and IT operations engineer at EQOM. First-year HBO-ICT, driven by the parts of computing most people skip.

I run a homelab because I'd rather own my own stack — Docker services, local LLMs, and tooling that stays under my control. I trade on IBKR, study for Azure certs, and shoot photographs as the other half of the same instinct: look closer, see more.

Everything I'm thinking about lives in one place.
