Software development as a hobby, it's about me.
I always try to be aware of the latest trends in programming, tools and IT in general. For me it's ok to learn new technology "just for fun" because I really enjoy what I do.
I participate in open source projects and listen drum and bass while coding.
I feel confident in MEAN stack but I'm used to solve an issue in best way without regard to my current knowledges. So it is absolutely not a problem for me to use any instrument that will be more appropriate in a given situation.
