Hey, my name is Hoan and I’m $\sum_{n=1}^{8} n + 1$. (do you really want to find it? )

Now I’m working for a bank as a network admin. My responsibility is monitor/troubleshoot/setup connections from branches to Head Office. I used to teach CCNA (a Cisco certified about network) at VnPro.

I’m a guy with curious mind, so I want to learn new things everyday. It helps me keep up with other people and make my brain always active.
