Excellent REST with Spring 2 day code-camp. A high speed tour through all the important stuff. Good tutorial material with clear explanations and plenty of relevant hands-on labs. Five star!

Jonathan Lister

Sang illustrated the core topics of Java Generic and Lambda. It strongly enhances my Java knowledge in detail. Lambda is brand new to me, I learned a lots from this code camp. And it was always a very good experience to watch Sang's demonstration on coding and resolve issues with his help in class. Many thanks to you, Sang!

Whenever I've attended Sang's codecamps or his tutorials, I can't appreciate enough the efforts he makes and goes out of his way to explain the details. In today's fast times, it nice to know that you can go to a reliable mentor who can teach you the latest technologies so easily, and who is also very affordable. There are many instructors out there, but Sang stands out for his humility and passion. Thank you Sang for your great service.

Why pay 4-digit $$, as it is said on the site, for courses when you get more out of it with just $xx-$xxx?! This would be the only bootCamp on Java technologies if I would ever be asked for recommendation. Sir Mr. Shin rocks!!
