I'm Abderrahmane Khbabez, a software engineer and competitive programmer. Most of the time I write software, and sometimes I write about it on my blog.
Interests
I love to build things, break them, and build them better. Curiosity does most of the driving. I'm interested in low-level concepts, cryptography, Linux, distributed systems, and backend development.
