Pär Sikö is a Java developer with a long and happy history that includes J2ME, Swing, and JavaFX. He's been working with Java since its inception and has tried everything from architecture and large enterprise systems to mobile devices.
As a developer, Sikö is curious and thorough and knows the importance of pixels and colors. He is curious to learn new things, growing as a human being in the process, and happy to teach and inspire others about it. Thorough to ensure that the quality is on par with expectations and, perhaps most importantly, to really understand something makes it so much easier and fun to work with. Pixels and colors have never been as important as they are today; everything is measured by its looks, and Sikö’s focus on making beautiful applications is a deliberate strategy that has paid off numerous times.
Sikö has been a busy speaker for the last couple of years, presenting on the international stage as well as at Swedish conferences. He was named a JavaOne Rock Star for his presentation in San Francisco 2011. For Pär Sikö, the key success factor in a presentation is mixing good content with a big portion of humor and he wishes that more people would dare to step away from boring bullet lists and do something new and creative when presenting.
