About Me

Who am I

I’m Pamitha Gayashan AKA Mr Terabyte. Experienced Software Developer, IT Consultant with a demonstrated history of working in the computer software & hardware industries. Director of a software company which provide custom software solutions in Sri Lanka.

Why with a crazy name?

Well I used “Mr Terabyte” as my In-Game-Name for multiplayer games. I thought it’s better if I use the same name for my tech stuff in WWW.

What am I doing here?

I love technology, and It’s in my veins. Since I’m a little boy, I was a tech guy, so why the hell can’t I have a website now? Not only that, I have some blog sites and YouTube channels managed by me. So yeah, I needed a website to a showing of myself. Everyone does that btw.
