About the Author
Martin Sikora has been programming professionally since 2006 for companies
such as Miton CZ and Symbio Digital in various languages, mostly PHP. Since 2012,
he's been freelancing, working on projects in Python, PHP, Dart, Objective-C, and
AngularJS. He's a Zend Certified Engineer and was a member of the winning team
at Google Dart Hackathon 2012 in Prague.
About the Reviewers
Lamoriniere Cedric is a software engineer and a graduate from a French
engineering school, who mostly uses C++ during his day job.
His taste for innovation has led him to try out a considerable amount of various
web frameworks, technologies, and languages.
Among these languages, he has taken a strong interest in the Dart language for its
ease of use and efficiency. It allows developers to get things done in a timely manner.
Rokesh Jankie graduated in 1998 with a master's degree in computer science
from Leiden University, the Netherlands. He specialized in algorithms and
NP-complete problems. Scheduling problems that can be NP-complete was his area
of focus. He started working for the University of Leiden, ORTEC consultants, and
Ponte Vecchio, and later, worked for Qualogy. At Qualogy, he used what he had
experienced till that point to set up a product. Qualogy works in the field of Oracle
and Java technologies. With the current set of technologies, interesting products can
be delivered, and this is what QAFE is (refer to www.qafe.com for more information).
QAFE Inc. has a very dynamic team, which works in an agile way (going to
production weekly, quickly adjusting to market needs, and so on). In the team,
they don't distinguish between senior developers and junior developers, but they
recruit very good software engineers. This gives a new dynamic to the team and
makes it a great experience on a daily basis.
Books that Rokesh has worked on include Dart in Action, Manning Publications, and
HTML5 and CSS Responsive Web Design Cookbook and HTML5 Canvas Cookbook,
both by Packt Publishing.
I'm very grateful to my parents and my wife for supporting my
enthusiasm for computer science. My 2-year old son inspires me to
be the best dad, and he makes sure that I work hard to create a better
future for him through the application of computer science topics in
daily life and by sharing my knowledge on this subject. Reviewing
this book is part of that journey.
Hans Van den Keybus is a Belgium-based Flash, Flex, and Google Dart
developer, working for his one-man company called dotdotcommadot.
Although he started off creating simple games and animations for some well-known
design companies, he got the most fun out of structuring the code behind it. His
main areas of expertise are OOP, design patterns, and microarchitectures.
Currently, he's working on a major project developed in Google Dart for his
customers MSC and Maersk.
Whenever he's not programming, Hans is probably playing some sketchy basement
with his even sketchier grindcore band.
Frederik Leonhardt is a tech enthusiast and software engineer with more than
5 years of experience in Java, Java EE, and related frameworks. He likes to delve
into new technologies, and he started using Dart with its first beta release in 2012.
He likes to contribute to the open source community and is currently working for
Catalyst IT, a team of open source technologists. In the past, he has worked as a
researcher for the Institute of Information Systems at the German Research Center
for Artificial Intelligence, where he published papers on recommender systems and
their application in the mobile health domain.
He recently moved to New Zealand and enjoys the relaxed Kiwi lifestyle and the
beautiful outdoors, especially for tramping and photography.
Marko Vuksanovic is a consultant who specializes in software development and
delivery. He received his master's degree in electrical engineering and computing from
the University of Zagreb, Croatia, in 2009. He is currently employed by ThoughtWorks
Australia, where he helps deliver outstanding products to clients. He has spent the last
10 years working with web applications, and during this period, he has been involved
in numerous open source, as well as closed source, projects. He is very active within
the Dart community and used to actively contribute to AngularDart projects. His
other interests lie in the information security and machine-learning spaces.
When not providing services to clients, Marko spends time acquiring new skills,
breaking things, reverse engineering, or enjoying some time off at one of Australia's
beaches or a nearby tennis court.
