I work has a solution architect, and have been training in one form or the other for the last 5 years. I am good at teaching those who are completely new to a particular topic. For instance, lets say you have been a web forms (dot net) developer all this while. However, you have been advised that you will be working on dot net MVC from the next project. In situations like that, where you are learning something entirely new but still wish to harness what you already know, I am the guy for you. Another instance would be, you are really now starting your journey into the wonderful but terrifying world of development (it could be android, web, iOS or Azure) and you want someone to ease you into this. Well, I am that trainer. I am patient, i can be wonderfully funny, use all sorts of dramatic examples and generally keep things excited.
