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).

Jakub Zuchowski

Jakub Zuchowski Agency Contractor

Ruby on Rails Developer

Poland - Tests: 5 - Portfolio: 7

I have been a Ruby on Rails programmer for almost 5 years now (since early 2010). I have worked with various Polish companies, including micro-teams and a Corporation. I focus mainly on back-end development, such as json based APIs and try to master the techniques of BDD. I am happy whenever I can break out of Rails` default presentation schemes, and complement its backend with a completely new presentation-oriented technology, like Backbone.js. Outside of Ruby I am interested in learning Python and (very recently) C. I have experience as both a team player and a self-sufficient developer. I always try to pursue the best solution and am keen on learning new technologies, especially when I can put them to practical use.
