A Computer Science graduate, who did 3 years of Mechatronics Engineering before that then realised that's not my place. So I switched major since I am not a tree and never regretted it! It's never too late to do something you really love.
So passionate about programming, it's not only my professional career it's also my major hobby besides reading and social activities/organisations/voluntary work.
A night owl like most programmers I assume!
