[top] Student Testimonials

Highly recommend this course for anyone who intend to build Android applications.

Nanda - Dreamer Corporation

I was very impressed by the teacher knowled of the subject. Excellent!

Andre - FRBSF

Android Bootcamp training was great. Sasa was very knowledgeable and covered a lot. I feel much more comfortable in both in Android and the Eclipse environment. Having good knowledge of Eclipse and Java helps you keep up, but snapshots of the work done is available throughout the day to keep you from falling behind. The class was definitely worth it.

Jesse - Minarik Drives

Great class. Too bad didn't have time to do the exercise together. Having exercise/labs is excellent idea though. If you come up to Seattle/Bellevue, pls let us, T-Mobile Bellevue, know.

Milton - T-Mobile

Great class. Would love to take the Apache one.

Chuck - Williams-Sonoma, Inc.

Not sure what to expect from the training but was very surprised by how well it was set up. Exactly what I needed. I am ready to work on my first Android app.

Thomas - AgentSolid

I had taken another class before with the instructor for this class, Aleksandar Gargenta, and he has demonstrated on multiple occasions that he is very well versed in the content he is presenting. I feel like I got a lot out of this course.

Andrew - Computer Sciences Corporation

Overall, this course was very well put together. The instructor was very knowledgeable. In a week I have a better understanding of Android than what I've been attempting to do in my free time for the past 6 months. I have also learned several tricks and best practice techniques that I would never have picked up learning on my own.

Adam - Department of Defense

It was good overall and did demystify a good number of fuzzy areas for me. Very organized which is appreciated and the sample code was useful. Thanks!

Chris - Apple, Inc.

Keep going with the charts and drawing! It very helpful! The course was very clear and interesting, adapted to both developers and administrators. The charts and drawings made a significant difference.

Laurent - Marakana, Inc.

Loved it! Great info... great instructor!

Michael - USP

Overall the course was great. The instructor really knows his stuff. I definitely learned a lot in just a week. Hope this is the beginning of great things!

Don - L-3 Communications

I found there was very little that could be done to improve this course, especially given the beginner level, the pace was just right and the amount of material covered was quite broad. I learned a great deal more from this class than I expected, especially given the very short term nature of the course. I really feel I was given a good fundamental understanding of Java. The instructor was clear, concise, worded himself clearly and unambiguously, and rigorously pushed the class to apply good coding practices. I would definitely take this course again if I had to do it over again.

Ignas - Xerox

The method used to teach concepts was very excellent. I liked Sasa's way of presentation. Recommend the course.

Jagadeesh - Fujitsu Siemens Computers, Inc.
