Radoslava Leseva Adams is a software developer and programming book author. Her affair with programming languages began in the early 90s, when her father handed her a book on Basic as a form of summer holiday entertainment. Since then she has built a career out of freely jumping between different languages and platforms, including C, C++, Delphi, Java, ActionScript, Objective-C and most recently Swift. She passionately hates wordy manuals and having to click more than once to do a build. Radoslava and her brother, Hristo, run EasyNativeExtensions.com and DiaDraw.com, where they help ActionScript developers do cross-platform programming with AIR Native Extensions.Dr. Hristo Lesev is a software developer at heart, passionate speaker, educator and entrepreneur. Having had long experience with C++, C# and ActionScript for desktop and mobile, lately he can be heard more and more often advocating for Swift as the latest and greatest. While not busy developing mobile apps, Hristo enjoys teaching other developers as an assistant professor at Plovdiv University, Bulgaria. He is obsessed with computer graphics and can be found coding 3D stuff late at night.
