Danny van Kooten

My name is Danny and I run ibericode, a small bootstrapped software company from The Netherlands.

I've been making a living from my products for well over 10 years now. On this site you can read some more about me and find links to a small selection of my work.

Alternatively, you can find me on X (Twitter), Mastodon, Github or LinkedIn.

As of 2026, I am available as a freelance PHP developer.
