About me

professional profile
and contact info

My name is Ernesto Serrano Collado and I am an IT problems solver from Yecla (Spain).

I am an active and dynamic person who likes facing trouble in an immediate and decisive way.

That is why I consider myself as a troubleshooter both staring at the screen and behind the desk when holding the screwdriver.

My Expertise

skills that I’m
proud of

I have worked as a server administrator, an expert consultant on free software, mobile application developer, web developer, computer technician and more.

However, I'd rather teach people how to fish instead giving them fish and feeding them for a day. This is why I've worked for social organisations in places such as Granada, Bilbao, Barcelona, Copenhaguen, Krakow or Athens, where I taught how to build and maintain IT equipment and I've helped building computer rooms using recycled materials turning them back into operation.

Nothing is pointless. Anything can be optimized and all troubles can be worked out.
