Who I Am

My name is Miguel Pragier, and I've been making software since 1996.
For each project I used a different set of technologies, addressing business demands.

I'm married, father of 2 boys, Polish citizen and I like to travel, to read, to write, gardering, cook, and - naturally - programming.
