return to people


Marcin Żelasko

If anybody told me a couple of years ago that I would became a programmer, I probably would laugh at them. But hey, here I am! Thanks to Codetain I got to know the IT world from different perspectives. Now, I’m a part of our awesome DevOps team. Every day I can see how much I learn and how we all help our company grow. I’m happy that with our work we’re contributing to make the tech industry more green — ecology is extremely important to me! When I’m not programming or spending time in nature, I’m probably playing basketball, reading fantasy novels or playing board games with my girlfriend. I’m also a huge video games geek!
