My Coding History

My Amazing Family

Sema Ilter

My Lovely Wife

Mert Demir Ilter

My Wonderful Son

Behind every successful man, there is a strong woman. Sometimes, there is also a one little man with them too if they're lucky. I love them more than anything...


Interesting scenes from my life


I've been playing with this band since 2006. Before that, 3 of us were also playing together in a different band called MYST.
NREASON has a sound like trash metal mixed with new metal souce or something. The only thing you should know about is, it's HEAVY!


This is my desk. I usually prefer to work at home. I've been using Linux and Mac since a decade and I still don't like Windowz. If you notice, I use my old ipad as a third monitor ;)


I love retro computers. I still hold an Amiga 500 and an Amiga 1200, they are the greatest computers ever made in the history.


I really enjoy playing with Mert. I spent almost all of my free times with him. Thanks god, he is a great guy!

Full-stack father

I'm a pretty talended guy, I can maintain a Hadoop cluster and a baby at the same time.


I have so much to say but I just want to say that I feel lucky to have her.
