Jeanfrançois Arcand has been working in software engineering for the last 18 years. He studied pure mathematics and worked for a Canadian research centre, doing mathematical modeling in C++ until someone in- troduced him to a new language called Java. He never stopped using it. Jeanfrançois worked for Sun Microsystems for almost 10 years, before writing one of the first NIO frameworks, Grizzly, Jeanfrançois also developed the Grizzly Comet Framework, which was an early way to implement asynchronous web applications. He then started the Atmosphere Framework, which brings portability across Servlet container and allows the creation of WebSocket and Comet applications.
