About Me

kamarudin — Mon, 07 Aug 2006 04:41:32 +0000

Kamarudin Samsudin live in Kuala Lumpur, Malaysia.

I am a Software Engineer but most of the time I’m dealing with DBA’s stuff. I need to maintain MySQL and Oracle databases. Sometime, I involves in web-based development team but not as coder, more as architecture implementer (install & configure servers and etc).
Because of my working nature, I’m very interested in MySQL, Oracle and Web-based technology stuff. Currently, I’m tried to implement MySQL Cluster and learn Ruby so it can be my 1st scripting language. My aims, I will be Certified MySQL DBA by end of this year and an OCA by next year.
I have BEng in Electronics with Computing Science from University Of Wales, UK.
