Hello, my name is Ahmed AbouZaid and this is my "lite" technical blog!

I'm a passionate DevOps engineer, Cloud/Kubernetes specialist, Free/Open source geek, and an author.

I believe in self CI/CD (Continuous Improvements/Development), also that "the whole is greater than the sum of its parts".

DevOps transformation, automation, data, and metrics are my preferred areas. And I like to help both businesses and people to grow.
