Software Engineer and reactive programming evangelist at Groupon. I wrote my first line of code in Java when I was 16 years old. Since then I was working on projects for companies like Nokia, HP or Credit Suisse. Even though Java is my main programming language I'm trying not to limit myself to it. I love exploring new languages, technologies and approaches. I'm a speaker, open source contributor and ex Wroclaw JUG leader.
