About

Hi, I'm Ian.

I am Ian Ketelings, a software engineer from the Netherlands, working across development, server management and cyber security.

Most of my work sits on the less glamorous side of software: backends, infrastructure and security. Integration platforms talking to more than fifty APIs, AWS environments, more than 25 Linux production servers, user-level encryption and security code reviews. That mix taught me to always ask what happens when something fails.

Because I do all three, I tend to catch the problems that fall between specialists: the feature that is fine until it is deployed, or the server that is fine until someone reads the code. Lately I also spend time on AI and apps, and I write down what I learn in plain language.

What I believe

Security is a habit.

It works when it is part of how software is built, and not a check at the very end.

Plan for failure.

Everything breaks at some point. What matters is whether you notice, and how fast you recover.

Boring is a compliment.

The best systems are the ones nobody has to think about.
