Maciej Zubala

Maciej Zubala Agency Contractor

Senior Ruby On Rails developer

Poland - Tests: 4 - Portfolio: 6

Software development is not only my profession but also my greatest passion and hobby. This is why I spend majority of my free time improving my programming skills, learning new concepts, technologies, languages and tools. I get the greatest satisfaction when products I develop are released to the world and people start using it - that makes me want to spend more time at work. When not in front of my monitor, I'm probably taking care of my daughter or doing some sports (tennis and swimming most of the time).
