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.

Been using computers since I was 6, and started using Linux at 9. I find networks and the Linux kernel interesting, anyway I would love to work at a physical data center one day.
