[top] Student Testimonials

The course was well put together. Some training courses don't plan out the Labs very well but this course did a great job of setting up clean well-defined labs that stayed on-point to the topic at hand. The instructor was extremely well prepared to teach the class as well as other parallel topics outside the scope of this course.

Brett - Walt Disney Animation Studios

The instructor was supremely knowledgeable, not only in the course material, but on android in general. Obviously, he is an astute developer in addition to being a course instructor. I especially appreciated the tips on best practice and coding style, and the instructor's willingness to address questions outside the scope of the course project.

Jeremy - Sandia National Labs

Sasa was great! Outstanding instructor...really knows is craft.

Scott - DISA DECC Mechanicsburg

Awesome experience. Best training course I've ever attended.

Jamie - Sierra Systems Group

This was a great training. The instructor was very well prepared and during the week he was able to keep the pace of the course at the right level.

Alexandru Catalin - Product Architecture

Great, fast paced class stuffed with information. If you're up for it, you'll get every penny out of your time.

Adam - xMatters

Every topic that I was looking for practice or deeper explantion was covered completely. Topics that I already had a good understanding of were explained further, and I was able to pick up details that I either did not know or had previously overlooked, which will help improve my future coding.

Joseph - Computer Sciences Corporation

The amount of stuff to be covered in this course is quite too much, but instructor covered pretty much all. The time can be extended of this course to cover it better. Amazing Course!

Bhagyashree - Xerox

The class was great and I learned a lot about good programming practice and how to do things properly in Android. I'm glad that there was a book provided for reference later. Sasa was very helpful and did a good job explaining things.

Jon - Sandia National Labs

Sasa is very knowledgeable about android development and provided excellent instructions over the 5day course. It is rare to have instructors that are capable of troubleshooting problems on their feet using very little time during the labs.

Ken - Sandia National Labs

Indispensible . Absolutely fabulous course. Learned so much even after using apache for 10+ years.

Steve - University of Guelph

Great course and instructor.

Thomas - Self

Wow! Really learned a lot. This course paid for it self 5 times over.

Forrest - Sacramento County

The breath and depth of the instructor's experience and knowlege was phenominal. The course was a great experience.

Darren - Research in Motion

Very knowledgeable instructor

Chidi - Hotels.com

Great class. I've learned a lot about the subject matter and would love to take another one in the near future. Thanks Sasa!

Roberto - Fresenius Medical Care

The course was unbelievable and the instructor really knew the information. I was amazed how quickly the instructor was able to figure out student problems and answer/address any problems or concerns presented. I learned so much from the course.

Michael (Mike) - Peerless Technologies Corporation

Sasa was an excellent instructor and very patient with our many work related interruptions!

Brett - SkillSoft

Overall though, Sasa did an excellent job in presenting the material and I do feel empowered to go and develop Android applications. I would definitely recommend this training to anyone interested in learning about Android.

David - HBO

The instructor is very knowledgable & precise in providing the required information.

Jay - Avery Dennison

This class changed my life. I will never be the same again.

Anthony - Pearson

fast pace, compressed learning.

Bastiaan - Intel Corporation

Overall, I thought the class was excellent. Sasa was very adaptable to the changing format of the class -- given that the class was originally focused on a pure programming class and changed to more of a high-level architecture class.

Samson - T-Mobile

I went from some weak, outdated Java skills to using and understanding some powerful frameworks. I learned much more than I expected. Training classes in general can be hit-or-miss, but this one with this instructor is excellent. He helped bring everyone up to speed and ensured we all understood the technologies involved.

Steven - UC Davis

This class was excellent! Sasa is a great instructor with a good understanding of theory, but also a top notch developer very familiar with the low-level details -- super impressive. This class exceeded my expectations. I learned so much. Thank you. :-)
Without exaggeration, I can wholeheartedly say that this was the best training class I've ever taken. Sasa was an outstanding instructor and demonstrated time and time again how well he knows Apache. I was truly blown away by how useful and informative it was. Highly recommended!

Brandon - Broward Community College

Great instructor very knowledgable, great course for beginners. Aleksandar was great, well-rounded instructor, has expertise in the Tomcat and Java. This is definitely one of the best technical training course I have taken! I'd recommend this class to other Systems Admin who wants to learn more on Tomcat!

Steven - Autodesk

The instructor and materials were excellent.

Dereck - Computer Sciences Corporation

This class was very helpful for me to learn the fundamentals of android application development. The course material was presented clearly and the concepts were defined in an understandable manner. I am excited to take what i have learned and start building apps! Thank you!

Chrissy - Tribal DDB

Nothing to improve. Sasa was very knowledgeable and no question was outside his ability to answer solidly and consise. Very enjoyable.
