Good content, Brian was friendly and really helpful.
Kieran - Junior Software Engineer (MSc) - Government - July 2023
Learned a lot from this course, especially the second day. The content was at a good level and I enjoyed building the 'tracks' project over the two days, especially enjoying how each new topic was integrated into the product iteratively. Brian's delivery was good and all concepts were explained well. Thanks!
