Coder. Husband. Father.
Hi there! I'm René.
A passionate web developer
I started programming when I was 13. As a huge fan of an anime called "Hunter X Hunter", I looked it up online and found some fansites. I was hooked and wanted to build one myself. That was my entry into a whole new world. I built my first HTML page and then another, and another, always asking myself how to improve it and make it more interesting.
Next, I bought a PHP compendium and learned how to create more dynamic web pages. During these days I started coding a guestbook then a newssystem, a shoutbox and other features for my website - good old times!
And now? I'm still a huge fan of Anime. Apart from that, I have developed way more skills over the years and fell in love with the PHP Framework Flow and Neos CMS.
In addition, I love to deal with security-related topics in web development. I am occasionally active as a security researcher and try to draw attention to vulnerabilities.
If you want to read more about my coding experiments and projects check out my blog.
What do I do when I'm not in front of a computer? I own and play a beautiful Jackson Monarkh SC heavy guitar. I also collect old Nintendo games.
