Every single semester, students had struggled with learning new languages and APIs but they eventually delivered amazing ideas with their own story with architectural decision and design rationales.
Got great feedback from 08-723 N6 student. Always detail feedbacks make me speculate what they want and how to improve my lectures. - Feeling happy.
"I had very good hands on with excitement working in both platforms.
I feel this course opened me up new windows for mobile software development.
Your lectures were up to the point and practical.
I will definitely recommend this course to my juniors.
Thank you again for your continuous support."
I love teaching in CMU when I got inspired by all the students who made tremendous effort to learn something knew and make something cool.
