Mykhaylo Rykmas

* You can call me Michael (English) / Michał (Polish)

I'm Ukrainian but I live in Krakow (Poland) since 2014 and I plan to stay here on permanent basics. I live there with my lovely wife and my 2 great kids. My main background for a recent years is MySQL DEV/DBA engineer but I'm also participating in wider range of tasks which could be likely called as DevOps task. My career highlight is: "Pasja to za mało" (polish), because our passion doesn't always guarantee that our personal and professional requirements will be met. Everyone is working to build his own career, but this world is not whole about money, so proper self-balancing and self-control are very important.

Apart from my work, I enjoy most of my time being outdoors. During the warmer months, I enjoy playing football, running, biking, motorbiking.

When forced indoors, I spend my time with my lovely kids and my wife, I play piano or guitar or spending my free time exploring the latest technologies.

Thanks for the patience if you're still reading this and have a nice day ;)
