Erik Beugelaar is a programmer who is focused on visual developer tools, giving a software designer the feeling that making software is an art because of the way the graphical user interface is built using the visual toolset.

After trying many visual developer tools during the last 10 years, LiveCode got his special attention in 2010. It was the natural language syntax that could express the way things could be done, and more specifically, the writing of English-like sentences had become an art too.

Nowadays, he is using LiveCode to examine and analyze data for financial purposes. As a developer of tools for other developers, he is looking forward to the Next Generation version of LiveCode.

Along with his fulltime professional career, he is also actively involved in voluntary projects in Kenya. Whenever possible, he promotes the educational value of using LiveCode in classes.

Guanhua Chen is a doctoral student at the University of Miami, majoring in Teaching and Learning (specialization in Science, Technology, Engineering, and Mathematics). He gained his Master's degree from the Learning, Design, and Technology program at the University of Georgia. His research is focused on the intersection between technology and STEM education. He is especially interested in utilizing various technologies as cognitive tools as well as innovative assessment instruments in science education.

Cecil Costa is a freelance developer and founder of Conglomo Limited (www.conglomo.es), which offers development and training programs. In his professional career, he has created projects by himself and has also worked for a variety of companies from small to large ones, such as IBM, Qualcomm, Spanish Lottery, and DIA%.

He develops in a variety of computer languages (such as C++, Java, Objective-C, JavaScript, Python, and so on) in different environments (iOS, Android, Web, Mac OS X, Linux, Unity, and so on) because he thinks that a good developer needs to learn every kind of programming language in order to open his mind, and only then will he really know what development is.

He has worked with LiveCode, creating educational music games for Acción Piano School in Spain. You can view some of his work at www.smartboardmusic.org.

Theo Heselmans is an IBM Champion for Collaboration Solutions. In 1993, he started working as a Notes/Domino consultant with Version 3. He delighted (and still does) many customers with custom applications (complex CRM systems, web content management solutions, project and document management, reporting, and so on).

In 2001, he founded his own company, Xceed (www.xceed.be), which is now a proud member of the Penumbra Group.

Since 2009, he has been responsible for Engage (also known as BLUG). During their events, he gives users, speakers, IBMers, and business partners the opportunity to share information, collaborate, and network. Theo visits other LUGs regularly and has been to 19 Connect/Lotusphere conferences.

He is an avid believer in all things social.
