About me
Hey, my name is Ivan and I'd like to tell you here some facts about what I am. I'm a software developer with an almost 12 years experience in Java, databases and some front-end technologies. Actually, Java is my primary language, but I'd like to try some new technology out of my work desk. My experience is heavily related to Big Data/Data engineering (Act as Data Tech lead for 5+ years). I try to share my knowledge at this blog, at Stackoverflow, at my Medium blog and as a speaker at technical conferences.
