Piotr KafelThe Groupon guy

Software Engineer at Groupon. I wrote my first line of code in Java when I was 16 years old. Since then I have been 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 an open source contributor and ex Wroclaw JUG leader.
