Leonardo Cecchi


In few words I can say that I and computer science have grown together. Programming has always been my passion. A passion that began when I was 6, standing next to my father, programmer, who taught me the rudiments of programming in C. At the elementary school I could write on the keyboard but not on paper! I've always been curious and I'm not enough satisfied to learn new technologies and new programming environments. Among them: Python, Java, Go, C, Haskell. Today I am part of the 2ndQuadrant Italia team because it gives me the opportunity to work on PostgreSQL, the DBMS that addresses innovative problems with a 'classic' language.
