Testimonials (4)
It was 1-on-1 so the training was specialized to my specific needs. Shane highlighted elements of WPF/C# that could potentially be beneficial to my development projects.
Warren Nolan - Northrop Grumman
Course - Programming in WPF
Trainer knowledge, involvement, and rapport
Adam Kuklewski - GE Medical Systems Polska
Course - Technical Architecture and Patterns
The explanations and interactivity of the trainer, he really brought the subject well; and even-though I was probably not experienced enough, I did learn a lot from it!
Pieter Bruynseels - Spot Buy Center BV
Course - Design Patterns
Nice and friendly. Very knowledgeable. Would recommend Shane to others.
