Hi, I am Great!
My name is Umegbewe (preferably called "Great").
I'm a Site Reliability Engineer with 3 years industry experience, my primary focus is ensuring the reliability, availiabilty and performance of critical systems.
My experience include designing and implementing scalable and fault-tolerant infrastructures, performing incident responses, and enforcing best practices for deployment, monitoring, and testing.
Outside work, I hack on the Linux Kernel and low-level stuff. I enjoy problem-solving and read books on software engineering, automobiles and finance.
I find networks and the Linux kernel interesting, anyway I would love to work at a physical data center.
