Joanna Lee loves technology. As she reviewed this upcoming unified communications book, she has also learnt a lot about this particular topic as well. Other than reviewing books, she also does game development. She has programmed for an action game, KengoZero on the Xbox360 and for a Massively Multiplayer Online Games (MMOG), Otherland, on the PC. She is a game designer and has a collection of game design/writings. Her interest in the mobile/web has led her to develop apps and games for these popular platforms as well. Do keep a look out for her apps/games when they are launched! Just a note, she is not just a tech mouse, she also loves food, travelling, taking photos and spending time with family and friends.
